Anyone got any advice for a armalite ar-10 t carbine with a 16 " match barrel reguarding ammo. Quite naturally match grade ammo is going to be my choice, but there are so many manufacturers of "good stuff" it is hard, not to mention expensive finding that perferct factory load. I would rather hand load but don't want to take the chance of messing up my gun. I know that i'm losing velocity with the shorter barrel, hence the bullet is falling faster. So anyone got any pointers?
