Now I know I dont reload any long neck rounds like for example Win 30-30, where you may want to trim the casings after shooting and before reloading. And stressing such as cracks and spliting could come into play. Just a general common sence view. But when it comes to pistol reloading for example, 357 mag, 9mm and 45 ACP. How many times can you reload....
357 mag
38 spl
9mm
45 ACP
Before it becomes to the end of their life. And depending upon the load powder charges that were used. For example a 9mm, for a 115 gr jackted round nose, I use Bullseye 4 grs start to 4.5 grs max.
124/125 gr lead round nose.start 3.8 grs Bullseye. 4.3 max.
I have been told that 9mm do not need to be trimed. And I have never had a problem. Where 357 mag may need to be trimmed more frequently. And I might add I only like to use the 357 mag nickel plated casings for reloading.
