I've mainly been using WWB, or S&B (230 - Ball) in my stock Springfield G.I. .... recently tried some PMC, and I noticed a definite difference, in the way it "felt". By that, I mean that it seems to be a bit "hotter" than what I had been using. The main thing I noticed, was the way it was ejecting. The PMC is tossing its brass a couple feet over my head, and to the right, and landing 4 to 6 feet behind me - consistently (excellent). With the Winchester and others, the empties would land only 2 -4 ft. behind - or to my right, or occasionally will drop one on my head, or at my feet. This was the case with both the factory extractor; and the Wilson that I just replaced it with. I tuned the extractor; smooth feed, no FTE's, or other problems. Could anyone enlighten me as to whether there is a significant difference in the loadings between PMC, and WWB or other brands .... also would anyone be aware of another brand of .45 - Ball, that is manufactured to similar specs as the PMC?
By "Hot", I wasn't specifically referring to the round's velocity .... possibly just chamber pressures (faster powder), which wouldn't necessarily result in a higher velocity. If this is the case, and it is just causing a slightly "stiffer" recoil - faster cycling - resulting in the "stronger" ejection I referred to .... I'm concerned that it might cause a bit more wear to the weapon. Because of this, I don't know if I'd want to use it (although I do like the more "positive" functioning characteristics). PMC, refers to itself as Military Spec" .... or at least they used to, back when the .45 was "G.I." & I'm wondering if loadings of the other brands are just 'softened up' a bit, for safety reasons (?) - or whatever.
BTW, with the PMC, I haven't noticed any signs of 'over pressure' .... i.e. primer flattening, cratering.
I know there isn't going to be a major difference in velocity, from brand, to brand (don't really care), however due to the "feel", and functional behavior using the PMC, there has to be a difference somewhere .... just trying to figure out exactly where it is.
...... Preciate any info

It shot eratically, misfires were common in all guns and with one round in one gun, the primer was the only thing to go off. Glad I was paying attention since it did not cycle and pushed the bullet about a half inch into the barrel.
