Never, in 59 years of reloading, have I worried about it.
What are you expecting to shoot with your .223? Deer, Antelope or are you looking for a home defense load? I found that a tough mono bullet like a Barnes X works best for me on 4 legged animals, I haven't had an opportunity on the 2 legged ones yet. Perhaps sometime after November 3rd. LOLI reloaded some .223 ammo for my son.
Is there a way besides ballistic gel to check penetration and expansion on a bullet?
I looked at making my own but don't think it is for me.
FBI stuff is too expensive.
How do you guys check your bullets.
Neither have I. I've hunted with a 30-30 and a 30-06 all been successful hunts. But on the other hand I do not hunt anything a 30-06 can not kill. Never have I ever worried about penetration, my father's and grandfather's word was good enough for me.Never, in 59 years of reloading, have I worried about it. Anything I load, as well as anyone else, is going to penetrate sufficiently for the purpose for which the bullet was cast or swaged for, providing sufficient propulsion.
