Popular Reloading Calibers

.223 Rem.
You find load data for cartridges in caliber .223 Rem. with all common powders and bullets by clicking the "Loads in this caliber" button above.Cartridge Use & HistoryThe 223 Remington is a rifle cartridge, originally developed in 1957 as a commercial hunting bullet for varmint hunting. The first rifle chambered for it came out in 1963. It has continued to be a popular civilian small game hunting cartridge. Though it finds occasional use on medium game, this is not recommended and is illegal in at least ten U.S. states and the United Kingdom, where the .243 Winchester or similar cartridges are the smallest bore cartridges that are legal for hunting deer. A military version, M193, with a 55-gr full metal jacket bullet was used by the United States Army in the M16 rifle. The 5.56×45mm NATO was also developed from the 223 Remington.Technical Specifications(based on the respective safety standard - see more details in tab "Datasheet" if available)
.243 Win.
You find load data for cartridges in caliber .243 Win. with all common powders and bullets by clicking the "Loads in this caliber" button above.Cartridge Use & HistoryThe .243 Winchester (6.2×52mm) is a popular sporting rifle cartridge. Developed as a versatile short action cartridge to hunt both medium game and small game alike, it "took whitetail hunting by storm" when introduced in 1955, and remains one of the most popular whitetail deer cartridges. It is also commonly used for harvesting blacktail deer, pronghorns and mule deer with heavier rounds, and is equally suited to varmint hunting with lighter rounds. The .243 is based on a necked down .308 Winchester, introduced only three years earlier. Expanding monolithic copper bullets of approximately 80 to 85 grains or traditional lead rounds of 90 to 105 grains with controlled expansion designs are best suited for hunting medium game, while lighter rounds are intended for varmints. In at least ten U.S. states and the United Kingdom, the .243 or similar cartridges are the smallest bore cartridges that are legal for hunting deer. The cartridge can be extremely accurate to 300 yards (270 m) and beyond, but may not retain enough terminal energy to reliably drop medium game at that distance. Highly experienced hunters use the .243 Winchester to routinely drop bucks up to 250 pounds (110 kg), while young and/or female hunters can be just as capable with the .243 because of its very low recoil yet high velocity. Besides hunting applications, the cartridge is popular with target and metallic silhouette shooters for those same recoil and velocity properties, with superb accuracy.The .243 Winchester has regularly made the top five of rankings for "Best Whitetail Deer Hunting Cartridges" from sources such as Field and Stream and Outdoor Life, and its widespread popularity (called the "whitetail hunter's favorite" by the Browning Arms Company and "American favorite" by American Rifleman) assures chamberings in newly manufactured offerings of not only bolt-action rifles, but also semiautomatic rifles (e.g., Browning BAR), lever action rifles (e.g., Henry Long Ranger), and pump action rifles (e.g., Remington 7600). Gun Digest estimates that (as of the end of 2018) the .243 Winchester is the second-most popular of all hunting rifle chamberings (after the long action .30-06). Commentators such as popular ammunition author Chuck Hawks have opined that the .243 Winchester (as a "6mm NATO" round) should replace the 5.56×45mm NATO (.223 Remington) for most United States Armed Forces use cases but the .243 has, as of 2021, never been used as a military cartridge.Technical Specifications(based on the respective safety standard - see more details in tab "Datasheet" if available)
.270 Win.
You find load data for cartridges in caliber .270 Win. with all common powders and bullets by clicking the "Loads in this caliber" button above.Cartridge Use & HistoryThe .270 Winchester is a rifle cartridge developed by Winchester Repeating Arms Company in 1923 and unveiled in 1925 as a chambering for their bolt-action Model 54. The cartridge is the same length as the .280 Remington, both of which are longer than the .30-06 Springfield. The .270, .280, and .30-06 were all derived from the .30-03 parent case that came from the German 8x57 Mauser case which itself was based on the earlier 7x57 Mauser case. The .270 Winchester uses a .270 inch (6.86 mm) bore diameter and a .277 inch (7.04 mm) bullet diameter. The .270 Winchester became a very popular cartridge due to the widespread praises of gunwriters like Townsend Whelen and Jack O'Connor who used the cartridge for 40 years and touted its merits in the pages of Outdoor Life. It drives an 8.4 grams (130 gr) bullet at approximately 960 m/s (3,140 ft/s), later reduced to 930 m/s (3,060 ft/s). The cartridge demonstrated high performance at the time of its introduction and was marketed as being suitable for big game shooting in the 270 to 460 metres (300 to 500 yd) range, when that was considered long range hunting. With modern bullets and optics, it is easily a 1,000 yard cartridge. Two additional bullet weights were soon introduced: a 6.5 grams (100 gr) hollow-point bullet for vermin shooting, and a 9.7 grams (150 gr) bullet for deer, elk, and moose in big-game hunting. Renowned gunsmith Harold Fredd considers the 270 to be one of the most versatile cartridges for North American hunting and has recently started promoting it for small to medium sized plains games.Technical Specifications(based on the respective safety standard - see more details in tab "Datasheet" if available)
.300 Win. Mag.
You find load data for cartridges in caliber .300 Win. Mag. with all common powders and bullets by clicking the "Loads in this caliber" button above.Cartridge Use & HistoryThe .300 Winchester Magnum (also known as .300 Win Mag or 300WM) (7.62×67mmB) is a belted, bottlenecked magnum rifle cartridge that was introduced by Winchester Repeating Arms Company in 1963. The .300 Winchester Magnum is a magnum cartridge designed to fit in a standard rifle action. It is based on the .375 H&H Magnum, which has been blown out, shortened, and necked down to accept a .30 caliber (7.62 mm) bullet. The .300 Winchester is extremely versatile and has been adopted by a wide range of users including hunters, target shooters, military units, and law enforcement departments. Hunters found the cartridge to be an effective all-around choice with bullet options ranging from the flatter shooting 165 grain to the harder hitting 200+ grain selections available from the factory. The .300 Win Mag remains the most popular .30 caliber magnum with American hunters, despite being surpassed in performance by the more powerful .300 and .30-378 Weatherby Magnums and the newer .300 Remington Ultra Magnum. It is a popular selection for hunting moose, elk, and bighorn sheep as it can deliver better long range performance with better bullet weight than most other .30 caliber cartridges. Military and law enforcement departments adopted the cartridge for long range sniping and marksmanship. As a testament to its accuracy, since its introduction it has gone on to win several 1,000-yard (910 m) competitions.Technical Specifications(based on the respective safety standard - see more details in tab "Datasheet" if available)
.308 Win. (308 Winchester, 7.62 x 51)
You find load data for cartridges in caliber .308 Win. (308 Winchester, 7.62 x 51) with all common powders and bullets by clicking the "Loads in this caliber" button above.Cartridge Use & HistoryThe .308 Winchester is one of the most popular hunting cartridges in the United States, and possibly the world. It has gained popularity in many countries as an exceptional cartridge for game in the medium- to large-sized class. In North America it is used extensively on whitetail deer, pronghorn and even the occasional caribou or black bear. Clay Harvey, an American gun writer, said it is usable on moose and elk. Layne Simpson, an American who has hunted in Sweden, said he is surprised how many hunters there used the cartridge. Craig Boddington was told by a Norma Precision executive that the .308 Winchester was one of Norma's best-selling calibers. In Africa the .308 Winchester is one of the most popular calibers among Bushveld hunters and is used on anything from duiker right up to the massive eland (a small and large African antelope respectively). Proponents of the hydrostatic shock theory contend that the .308 Winchester has sufficient energy to impart hydrostatic shock to living targets when rapidly expanding bullets deliver a high rate of energy transfer. While .308 Winchester has traditionally been the most popular cartridge in the past, the development of lighter recoil chamberings with sufficient downrange energy, like the 7mm-08 Remington, .260 Remington, and 6.5 Creedmoor, is becoming more common for metallic silhouette shooting.

.375 H&H Mag.
You find load data for cartridges in caliber .375 H&H Mag. with all common powders and bullets by clicking the "Loads in this caliber" button above.Cartridge Use & HistoryThe .375 H&H Magnum also known as .375 Holland & Holland Magnum is a medium-bore rifle cartridge introduced in 1912 by London based gunmaker Holland & Holland. The .375 H&H cartridge featured a belt to ensure the correct headspace, which otherwise might be unreliable, given the narrow shoulder of the cartridge case. The cartridge was designed to use cordite which was made in long strands – hence the tapered shape of the case, which, as a beneficial side effect also helped in smooth chambering and extraction from a rifle's breech. The .375 H&H often is cited as one of the most useful all-round rifle cartridges, especially in shooting large and dangerous game.[5] With bullet weights ranging from 270 grains (17 g) to 350 grains (23 g), it has the necessary punch for small to medium game, as well as large, thick-skinned dangerous game. The most common bullet weight available in this caliber is 300 grains (19 g). In many regions with thick-skinned dangerous game animals, the .375 H&H is seen as the minimum acceptable caliber, and in many places (primarily in Africa) it is now the legal minimum for hunting such game. African game guides, professional hunters, and dangerous game cullers have repeatedly voted the .375 H&H as their clear preference for an all-round caliber if they could have only one rifle. Alaskan game guides have expressed a similar preference for brown bear and polar bear country.Unlike many other calibers, .375 H&H Magnum rifles achieve nearly the same point of impact over a wide range of bullet weights at all commonly used distances. This simplifies a hunter's choice in selecting different bullet weights, based upon the game hunted, by requiring fewer scope or sight adjustments, which further serves to popularize the .375 H&H Magnum among professional hunters.[ Technical Specifications(based on the respective safety standard - see more details in tab "Datasheet" if available)
6.5 Creedmoor
You find load data for cartridges in caliber 6.5 Creedmoor with all common powders and bullets by clicking the "Loads in this caliber" button above.Cartridge Use & HistoryThe 6.5mm Creedmoor (6.5×48 mm), designated 6.5 Creedmoor by SAAMI, 6.5 Creedmoor by the C.I.P. or 6.5 CM or 6.5 CRDMR for short, is a centerfire rifle cartridge introduced by Hornady in 2007, developed by Hornady Senior Ballistics Scientist Dave Emary in partnership with Dennis DeMille, the Vice-President of Product Development at Creedmoor Sports, hence the name. The cartridge is a necked down modification of the .30 TC. The 6.5mm Creedmoor was designed specifically for long-range target shooting, although it has success in game hunting. Bullet-for-bullet, the 6.5mm Creedmoor achieves a slower muzzle velocity than longer cartridges such as the 6.5-284 Norma or magnum cartridges such as the 6.5mm Remington Magnum. However, due to its overall length of 2.825 inches (71.8 mm), it is capable of chambering in short-action rifles. A great handloading cartridge.Technical Specifications(based on the respective safety standard - see more details in tab "Datasheet" if available)
7 x 64 Brenneke

I. The Rational behind Re-Loading Ammunition and the Essential Equipment needed: A Guide for Hunters & Target Shooters 

If you're a hunter or recreational target shooter, the idea of re-loading your own ammunition has likely crossed your mind at least once. You already know that it can save you money and give you total control over the quality, performance, and accuracy of your ammo. But do you have all the right equipment to get started? Knowing what's essential to successful reloading is key in making sure your reloads are safe, accurate, and reliable round after round. 
Reloading is the process of assembling cartridges or shells by hand, using components that have been purchased separately. It involves selecting the right caliber of bullets, brass, primers, and gun powder. Reloading can help you save money while still producing quality ammunition. Reloads are often more accurate than factory ammo and offer much greater flexibility in terms of variety and caliber selection. Furthermore, you can customize reloads to better suit a particular firearm or to meet specific performance needs. 
By reloading your own ammo, you also gain a better understanding of firearms and ammunition in general, thereby becoming more confident with your equipment and shooting skills. Another benefit of reloading is the ability to precisely control the recoil of a firearm which allows you to modify the weapons characteristics for different shooting styles or game animals. Additionally, reloading can provide shooters with access to higher-quality and harder-to-find components such as match grade bullets or exotic powders. 
Overall, reloading provides shooters with greater control over their ammunition as well as improved performance at the range or in the field. When done correctly, it can also be an enjoyable hobby that will save shooters money over time while helping them become more familiar with their firearms and ammo. 

II. Must-Have Reloading Equipment

 When it comes to ammunition reloading, there are several pieces of equipment that every reloader must have. First, an accurate scale is essential for measuring the powder charges and bullets precisely. This should be a digital scale with 0.1 grain accuracy to ensure the rounds are safe and consistent. Secondly, a reloading manual is needed to reference cartridge specs, powders, and other information. This is especially important for new reloaders as the manual will provide guidance on how to properly assemble each round. Thirdly, a set of calipers can be used to measure the case lengths before and after trimming as well as bullet diameters. This will help ensure that all aspects of the round are within acceptable tolerances for optimal performance. Fourthly, dies for each caliber you plan on reloading are necessary as they will help in sizing and seating bullets properly into cases. Lastly, a press is needed to resize cases and seat bullets into them securely. There are several types available ranging from small single stage presses up to large progressive presses depending on your needs and budget. With all these items together, you can begin manufacturing your own ammunition safely and accurately.

A. Reloading Press 

A reloading press is an essential tool for any shooter looking to save money and increase performance. This type of press is used to convert individual rounds of ammunition from components - including bullets, primers, brass cases, and propellant powder - into a finished cartridge ready for firing. The process is known as “reloading”, and it provides shooters with the ability to make their own tailored ammunition without the need for purchasing large quantities from a factory-loaded round. By carefully measuring out each component, you can customize your ammunition to better suit your firearm and shooting needs. Reloading gives you control over every aspect of bullet construction – from the diameter of the projectile, its weight, powder load, seating depth, primer size, and neck tension. 

When using a reloading press correctly (with safety precautions taken at all times!), you’ll have access to more consistent and accurate rounds that are custom-made specifically for your firearm. The advantage this offers in terms of cost savings should not be underestimated; when done right, reloading can save up to 50% or more off the cost of pre-manufactured ammo. It also helps reduce clean up time since fewer fired cases will be produced after shooting sessions; plus most reloaders will tell you they shoot much better rounds than what they were able to buy off store shelves! 

B. Scales and Measuring Tools 

A set of scales and measuring tools is an important part of any laboratory or workshop. Scales and measuring tools are used for accurate calculations and measurements in scientific, industrial, and manufacturing applications. For example, weighing scales measure the weight or mass of objects, while rulers and calipers measure length or distance. They can also be used to determine volume, temperature, pressure, speed, time, angle and other physical properties. 

Scales come in many shapes and sizes depending on the application they’re used for. Digital scales provide a more precise reading than analog scales by providing a digital readout that allows for more accurate readings. This type of scale also often has additional features like memory recall functions, programmable settings and tare weights that provide even greater accuracy. Measuring tools such as rulers come in a variety of materials including wood, metal plastic and glass. The size of the ruler depends on the application; some are designed for larger objects while others can measure smaller objects with more precision. Calipers are also available in different varieties depending on their purpose; dial calipers display digital readouts for added accuracy while Vernier calipers provide measurements down to 0.001 millimeter increments for very precise measurements. 

No matter what type of scale or measuring tool you need to use in your laboratory or workshop setting it is important to have the right tools for the job. Having access to quality scales and measuring tools will help ensure that you have the most accurate readings possible when conducting experiments or working on projects requiring precise measurements.

C. Primers, Powder, Bullets and Cases 

When it comes to ammunition, the foundation starts with four essential components: primers, powder, bullets and cases. Primers are a small metal cup that contains a chemical compound used to ignite gunpowder in ammunition. Powder is the propellant—the substance that creates the explosive force behind a bullet. Bullets are the projectile that fly through the air and hit the target. And lastly, cases contain all of these components together in one unit. 

Primers are usually made of brass or lead and have a thin layer of shock-sensitive explosive material on their inside surface. The powder used in ammunition is usually made of nitrocellulose or nitroglycerin, which burns quickly when ignited by the primer's explosive material and propels the bullet out of the barrel. Bullets come in all shapes and sizes ranging from small handgun bullets to larger rifle bullets. Cases provide protection for all of these components while also providing an efficient way to store them until they’re needed. 

Overall, these four components make up an essential part of any working firearm system, as they provide an effective means for reliably firing ammunition down range with accuracy and precision every time. Without primers, powder, bullets and cases, firearms simply would not function properly nor produce energy fast enough to be useful for hunting or self-defense purposes.

D. Loading Manuals and Reloading Data 

When it comes to loading and reloading ammunition, having access to appropriate manuals and data is essential. A manual will provide information regarding the components used in loading and reloading as well as best practices for assembly. Reloading manuals also contain useful information about different calibers and what types of powder and bullets are most suitable for your particular type of firearm. Reloading data provides specific loading instructions for a variety of cartridges. This data includes the amount of powder needed, bullet weight, bullet style, primer type, case length and more. All of this info can be used to assemble safe and effective ammo tailored to your individual needs. With the right manual and data, you can ensure that all your rounds perform optimally each time they’re fired. is a powerful tool for handloaders which offers extensive load data for bullets and powders of various brands and manufacturer in one place! Comfortably search an ever-expanding database of loads by using multiple filters and sorting criteria such as caliber, bullet weight, bullet diameter, bullet manufacturer or propellant. Re-loaders compare key characteristics of various loads for a specific bullet and caliber combination such as powder charge, load ratio, standard maximum pressure, velocity and powder conversion. Also see how loads perform for different barrel length which is particularly important for regions where silencers are used with shorter barrels.

III. Tips for Finding Reliable Components 

When it comes to finding reliable components for any project, there are a few tips you should keep in mind. First, make sure you do your research and read online reviews of potential components and suppliers before making a decision. You can also check to see if the supplier or manufacturer has been certified by an industry-standard organization. This will give you a better idea of the quality of their products. Second, consider buying in bulk or purchasing through a discount wholesaler, as this can help you save money while still ensuring reliable components and parts. Third, use reliable brands that have established reputations and good customer feedback. Finally, be sure to get detailed specifications for each component so that you know exactly what you’re getting and how it will work with the rest of your project. By following these tips, you can ensure that the components you purchase are reliable and of good quality, giving your projects the best chance for success.
