I'm loading .45 Colt 250gr Lead Flat Point Oregon Trail Laser Cast bullets into Winchester Brass with 7.0gr Win231 and Win LP Primers. No indications of over pressure on the brass or the primers, and no measurable bullet pull on the 6th loaded round after firing the first five (RBH 4.5"). After 50 rounds the barrel cleaned up fine with a single pass of a bore snake, except for the forcing cone, which was heavily leaded.
Can anyone explain the reason for this? How serious of a problem is this in terms of shooting pressures, etc.?
