Large Rifle (LR) Primers
Primers are a key ammunition reloading component. They are needed to ignite the powder charge.
There a seven primer sizes which differ by use (pistol vs. rifle ammunition), size (small vs. large) and force (normal vs. magnum): SP = Small Pistol Primers | SPM = Small Pistol Magnum Primers | LP = Large Pistol Primers | LPM = Large Pistol Magnum Primers | SR = Small Rifle Primers | LR = Large Rifle Primers | LRM = Large Rifle Magnum Primers.

Large rifle primers are designed specifically for larger cartridges such as .30-06 and .308 calibers. They have an increased power output requirements and are slightly larger than standard handgun and shotgun primers. This type of primer must contain more pressure when struck by a firing pin as well as generate more heat for it to ignite the propellant in cartridges when fired.
The components inside large rifle primers consist of a metal cup, typically made from brass or nylon, filled with a combustible powder made up lead styphnate, antimony sulfide, barium nitrate and other chemicals depending on the manufacturer, and held in place at the bottom of the cup by an anvil which is hit by the firing pin to spark off the primer mix.
Manufacturing large rifle primers involves several steps just like any other type of ammunition component. First, cups are made out of sheet brass or nylon then pressed into shape with metal tooling dies and punches before they are filled with a measured amount of primer mix either manually or using automated machines such as progressive presses. Each cup's anvil or steel plug closure stem is soldered closed before crimping onto each cup end either an aluminum disk foil sealer (for rimfire) or epoxy resin sealer (for centerfire).
It’s important always to use quality primers specifically designed for your gauge size since moisture can cause unreliable ignition timing which can lead to misfires. Improperly functioning primers can be dangerous so make sure you choose them wisely if you want your firearm to perform reliably every time you pull the trigger!
