    For AR's do you crimp? I seen some say yes and others say they never do. One even mentioned that any bullet with a cannelure will not be used? So whats says you? Will it cause any issues with bullet set back or functioning. Mine you this will be brass fired in the same AR and used over. I was always under the impression that all semi's and lever actions required a crimp?

    I have crimped and not crimped and it doesn't seem to make a difference.

    The question comes up about once a month. Half the members here crimp, the other half don't. I put a slight crimp on mine.

    I don't bother any more.

    It doesn't set back so much as it gets yanked out a few thousandths when it comes to an abrupt stop in the chamber. Kinda like an inertia bullet puller.

    Yep, so I am in the slight crimp IF there is a cannelure camp.

    I crimp all 223's that have the cannelure. I sometimes taper crimp heavy bullets that have no cannelure.

    I crimp all my auto-loaders with the Lee Factory Crimp Die cannelure or not. It not only helps secure the bullet it also increases accuracy.
    Here is a little accuracy test, LFCD vs No crimp. Note the slight increase in accuracy.

    I never crimp my .223, even though most of the bullets I use have a cannelure, never had a problem in my Rock River and I get very good accuracy.

    No crimp here, with or without cannelure. I own a Lee FCD to apply a crimp and didn't like the way it worked the neck. I wasn't testing for accuracy, so no comment on that aspect.
