I have found that any crimp not in the cannelure of the bullet or if the bullet does not have a cannelure, the crimp really puts my accuracy over a barrel, or I mean you could cover the group with a 55 galon brl. BUT, I have found a small, slight crimp in the cannelure of a bullet does not affect accuracy very much. Once again that is a small, slight crimp.<P>As far as using more powder than a manual say is MAX, I have done it, but it is MAX in some manuals and NOT in others.<P>I Personally, would start atleast 5 grains below the LOWEST suggested MAX charge with the given wt bullet I am using.<P><BR>HELPFUL HINT: (or atleast what I do.) On the VERY first shot of testing ANY loads, (even the one with the least powder in it) I check and double check that case for pressure signs. As you so eleoquently pointed out, the MAX in one manual is not the MAX load in another. Unfortunately I have had to disassemble a few rounds because my first shot, at what I thought was a good low safe pressure, was not.<P><p>[This message has been edited by blammer (edited March 24, 2001).]
