Steve, your comment "What are your credentials? Other than your ability over-over crimp with the LFCD." One of them is not making assumptions such as this one you just made public. For all you know and me too, for that matter, maybe I was under-crimping them such that instead of creating a smaller varible in a low extraction force needed to get the bullet out of the case, I was creating a large variable in a greater one. I've seen nobody's numbers as to the extraction force the LFCD has toset up for the bullets. Lee doesn't even mention such stuff.
Enlighten me, maybe I just did it wrong. What extraction force level and tolerance should bullets have?
