I was sitting on my throne (aka toilet) the other night and grabbed a Lee Reloading catalog that I had laying around to thumb through.
When I got to the crimping die, in the description it said something that was interesting. It stated (I'm paraphrasing) that the reason one would seat a bullet to the lands is to create consistent pressure when the round goes off. Using the crimping die negates the need to seat the bullet out to the lands.
Now I reload for an AR-15, a M1 Garand, and my bolts. Based on what Ive read on the interwebs it seems most never crimp for the semi-autos but a few do and swear by it. Crimping for a bolt apparently is never done except for the occasional hunting load.
So.. is this just marketing BS or is there some merit behind this?
In my own experience, I've been putting a light crimp on my AR loads but have not really experimented with crimp vs no crimp.
I have noticed that my reloads on the m1 garand grow ever so slightly if I chamber a round and then eject it without firing so I have been thinking about picking up the crimp die for the garand. I may have to experiment with one of my bolts.
