I have never used a crimp on rifle round that go into a bolt action rifle. Nor have I ever crimped a .223 round that was ging into an AR. I have never had the need to. They hold just fine with neck tension.
I have 3 sets of rifle dies that allow for a crimp if the reloader wants to. I tested crimped rounds, against uncrimped rounds. The uncrimped gave more consitint groups. That has been my experienc. YMMV
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
