Make sense. Thanks. I guess I'll be buying more stuff because I'll be reloading rifle ammo as well.KBCraig wrote:Because brass stretches when the cartridge is fired. Resizing doesn't always return it to spec.KinnyLee wrote:I don't understand. Why would one be trimming their rifle brass?
It's always a good idea to segregate your brass to specific rifles (if you have multiple rifles in one caliber). Chambers always vary. If you keep your brass sorted, it's already fireformed to that chamber. You can neck-size only, and greatly extend the life of your brass. Even then, you'll occasionally need to bump the shoulder back with a full length die, and/or trim the length.
