2 or 3 die for rifle

#1 · March 24, 2011, 1:21 am

ok, Im new to reloading and could probably find this info in a loading manual, but I'll ask you all first. What is the difference in choosing a 2 or 3 die setup for rifle. I will be loading for .308 (SA NM M1A) for service rifle matches and .223 (AR15)for service rifle matches. Both obviously are mag fed.

Thanks,

Andrew

If you are using a bullet without a cannelure, I would experiment with no crimp at all vs. a light taper crimp to see which gives the best accuracy. You don't want to apply so much crimp as to physically deform the bullet, this degrades accuracy.

basically the 3 die set gives you a crimping die which you really don't need if firing a bolt action ,,but for semi auto rifles its nice to crimp the bullet in place so when the bullets chamber themselves the bullet will not move or loosen,,,i only use a resizing/depriming die,,and a bullet seat die for my bolt actions ,,but on my semi autos i use all 3 dies,,,hope this helped
