I am new to reloading, but I had a friend walk me through the process and loaded 100 of .45 Colt. About 70 of those were 250 gr Rainer Lead Safe and the other 30 were Cast Performance 395 gr hard cast over 18 gr H110 and Federal Large Pistol primers. The problem is when I shot the 395 grainers the H110 seemed to burn quite dirty. Much more so than the 250 gr over Titegroup.
First question - would switching to magnum primers help the H110 burn cleaner? Or does that create more problems than it solves?
Second - I've also got a 300 WSM that I want to work up some varmint/wolf loads for. What is a good bullet in the 150 - 165 grain range? This will be over IMR 4350.
Third - I have a Sig P239 and it seems the chamber is not fully supported. Is this much of an issue with the 9mm?
Thanks for all your help!
