If you hand load a .308 round (175g Sieraa Matchking), for sue in an autoloader, you want to ensure that neither recoil nor feeding will set back the bullet.
I've been told by more than one source that an interference fit of .003" between the bullet and the case is sufficient.
But, to quality check a batch of rounds, you would check to see how much force is needed to set back the bullet if you apply the force to the tip of the bullet, while the base of the case is against a rigid support, right? (like on a K&M Arbor with force measuring kit).
How much force should it take to set back the bullet?
