I like what he said about crimp. Never liked crimp in a rifle load.

When using iffy quality brass, a crimp actually improves dispersion.
That only works if the bullets in question have a cannelure. Also, you are then licked to a specific overall length.

If you dont overdo the pressure the Lee Collet Crimping Die helps with better grip and reduces ES. You don't need a cannelure.

With the difference in springback between lead and brass, crimping non-canelure brass does not give much improvement. And, when overdone, reduces neck-tension.

And I believe it increases bullet failure when used on the edge of what a cup and core bullet can do. Produces a failure start point in the bullet.
