Hi all,
New to reloading so forgive the stupid questions
I've recently picked up some Hornady A-Max and Hornady SST bullets for my .308
The A-Max bullets have regular old flat sides, but the SST bullets have the grooves for crimping the brass into the bullet.
What's it for basically?
Should I be sticking to crimped bullets or some reason? Obviously there are plenty of bullet types which don't use it so what's the story?
