Here's my problem - I know that .45auto head spaces off the case mouth so a light crimp is typically recommended.
I also know that Browning was born in a nitrocellulose explosion of awesome and genius. Seems to me, that as long as the gap between the rim thickness and the extractor groove cut doesn't exceed the firing pin protrusion then the head space really doesn't matter as the case is held against the breech face. Isn't that one of the reasons it's so dang reliable?
So, my problem. When I perform a light crimp, I notice that when I cycle my rounds through my 1911, the bullet gets pushed back sometimes as much as .05". A heavier crimp seems, to me at least, to be the only way to prevent that.
Am I correct that 1) That's the obvious solution and 2) it won't really effect the head space and, therefore, performance of the rounds?
Or am I missing some other mistake that I'm making that causing this back seating of the bullets?
