my two cents for what it's worth
Yes, ArmyRat, in *MY* opinion only.
If you're shooting a straight walled case, when you "bell-mouth" the case you need to crimp it anyway... So even if you were using a jacketed slug, you're going to "crimp" the case against the side of the bullet, whether you crimp into a cannelure, a crimping groove (most cast pistol bullets have a groove) or simply seal the case against the side of the bullet. I realize that doesn't answer your question completely.
But, I think, NOTE I said think, that when you're using cast rifle bullets that the same principle applies. I've never shot cast bullets in any sort of rifle. For that matter I've never cast rifle bullets.
If you're shooting reduced loads in a rifle, I would *think* that the recoil isn't going have the same level of effect, since you're not going to be shooting a heavy magnum load, etc.
But to tell the truth I am convinced there are some *HIGHLY* experienced cast bullet rifle shooters on here that can definitively answer your question, where as I'm almost guessing here.
Hope this helps,
Jim

But I think they would still have some slack. Would proper neck tension itself be enough to stop the cast bullet from pulling out of the case from inertia. My Lee dies apply a roll crimp. I may possibly have to get the Lee Factory Crimp Die to apply a crimp on the bearing surface depending on bullet seating for correct OAL.
