Crimp .308 for SA?

[Ryninger]

When loading .308 for use in a magazine fed semi-auto is a crimp advised?

i would think that would be for tube feeds only...

I would crimp. The rounds could develop some set back from the recoil.

You could load up a mag and fire a few rounds, them remove them and measure the unspent rounds.

Crimp helps hold the projectil in place while sliding up the feed ramp and helps hold it in place as the powder starts to burn,so pressure can be built up BEFOR the projectiles starts to move, so you can get all the pressure of the powder transferre to the bullet

SA, I always put a little crimp on. Bolt gun ammo, not so much
