And if you can't load a round that does not need to be crimped you are also doing something wrong.

Depends on the Bullet

I honestly think it depends on the bullet. Those stubby little 147gr Winchester FMJBTs in .30 caliber are awful, IMO. I HAVE to crimp those for ANY rifle to get them to stay seated. Cycling a couple of dummies through a 1903 bolt gun had the bullets spinning silly.

With something like a 168gr Matchking, I don't crimp, or if I do, very, very lightly, as suggested. The 168 has a fairly long bearing surface and a case with good neck tension will hold it tight.

Insufficient neck tension worries me more than whether to crimp or not.

FWIW, I seat my long range AR loads about .010" from the lands, uncrimped, and they extract just fine. My short line ammo has much more space to jump than that. I seat those long enough that .007" of jump would make them just barely able to clear the magazine, and I've ejected and reused these before too.

Like I said, depends on the rifle and load. For an M-1, with stubby bullets, I'd do it. Quick and simple peace of mind. (And it really doesn't tkae long to crimp up a batch of rounds, IME.)
