In the constant search for accuracy coupled with reasonable velocity, there are some tools that assist in making the cartridge case a better vessel to contain powder primers and projectiles.
The sometimes-overlooked issue is that of case length. Cartridge cases under the influence of great pressure tend to stretch, to some extent the amount of length increase is a factor of both case design and cartridge intensity.
Older designs tend to stretch more. It is necessary to be aware of this and check each cartridge after every firing. There are several types of mini lathes on
