I have been practice loading to set up my dies for .223 Rem. Is the bullet held by friction or crimp. I'm used to roll or taper crimping when reloading pistol ammo. I'm a newb to rifle reloading.
It also depends what your goal is. Crimping can improve ES with your handloads sometimes. A friend that I shoot with all the time has a heavy barreled 223 rem, and he was able to use a light crimp as the final step to get the ES down to single digit numbers measured with a labradar, thats after weight sorting brass, annealing, neck turning, etc, etc.... His handloads with 75gr Amax's are incredibly consistent and accurate out to 550yds. Sometimes the crimping can improve consistency with bullet release.
Lee factory crimp die would be the way to go if you choose to.
What about crimping for reloading in a revovler? To crimp or not to crimp?!?

If a crimp improves your accuracy, then your neck tension isn't adequate.
If you're using a collet die, crimping is I think necessary because the neck tension is not all that high. I've experienced bullet set back from recoil slam in the mag box from collet die sizing with no crimp. Neck sized or FL sized brass should be okay though.
I agree, but sometimes it's tough to get adequate and consistent neck tension without causing concentricity problems with the brass. Thats why a crimp can sometimes solve the problem without causing others.
I simply use a smaller diameter neck bushing to fix the real issue, rather than resorting to a band aid like crimping.
I agree again, that can work, but it can also cause inconsistent concentricity during seating with the higher neck tension. I know that can be solved with more expensive seating dies and presses, but my point is excellent results can happen using affordable equipment and good techniques.
I don't consider a crimp a "band aid" when it can produce consistent and repeatable results.
Isn't crimping a form of neck tension? Isn't the goal of neck tension to hold the bullet in the brass at a specific overall length and release that grip at a consistent chamber pressure? I'd say if a crimp helps achieve that in some situations then it's not a band aid.It's a band aid when the real issue is neck tension, and you aren't resolving the real issue.
