A new kit allows reloading of fired .22 LR cartridges.
The effects of different primers on ammunition accuracy is a topic that interests many, but which relatively few can easily test with precision. Most competitive shooters are limited in their access to a 1000-yard range and a quality accuracy-testing facility. Thus, experimentation with primers is often done at shorter ranges, relying heavily on chronograph results to help select primer brands or lots by velocity uniformity and accuracy testing.
Pro shooter Josh Lentz shares more of his top tips for revolver competition.
In Part 1, we measured the pre-firing bearing surface length. When the bullet is thrust forward upon ignition, it is pressure-swaged to fit the bore.
How to avoid pressure problems when developing loads.
