Didn't mean to come across as a wise guy, in my last post.

This thread is one of the most articulate, and educational , on this subject that I've ever read anywhere, and sincerist thanks to all who are contributing.

I guess what's got me Buffaloed ( pun intended )....is that , given the outrageous compression levels that some use from time to time ( me included), ...and that , whatever the granulation started with, the charge becomes a crushed, jammed very solid plug...
Why the aversion to 4fg? I'm not saying that those compression levels produce the best accuracy, they seldom do. I just don't see where all the pressure can come from, based on granulation alone. <img src="/ubbthreads/images/graemlins/confused.gif" alt="" />

Guess I'm missing something here, and will continue to study the really good writings here.

Thanks again, GTC <img src="/ubbthreads/images/graemlins/cool.gif" alt="" />
