About US

What we are ...

XXL is a powerful tool for handloaders which offers extensive load data for bullets and powders of various brands and manufacturer in one place! Comfortably browse through the database by using multiple filters and sorting criteria such as caliber, bullet weight, bullet diameter or propellant type. Re-loaders compare key characteristics such as charge, load ratio, maximum pressure, velocity and powder conversion. Also see how loads perform for different barrel length which is particularly important for regions where silencers are allowed. All the loads are developed and reviewed by our pro staff. They regularly add new loads to the database. Feel free to suggest loads should you miss any. Also review and compare details about the bullets, cases and propellants used for the various loads to find your most suitable combination.


Who we are ...

We are a group of enthusiastic American, French and German hunters, engineers, lomg range shooters and reloaders who did not find the desired resoures and decided to start and operate this wesite.


What makes us unique ...

Our highly sophisticated ballistics calculator  takes all relevant aspects into consideration such as powder characteristics, bullets and cartridge dimensions. The underlying models are extensively covered in the relevant literature. The specifics are to calibrate these models to real tests in order to improve the accuracy of the models. We have worked with one of the most well-known experts in this space to fine-tune our models and calculator for best results.

Other existing ballistic calculators on the market are often developed based on very old programming languages and limited calculation capabilities of historic computers. Our models run on high end cloud servers which allow us to run many more iterations for more accurate results!
