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

I handload for all my calibers and for my Ruger Redhawk in .41mag the PMC brass gives me the best overall accuracy, consistiently, with all others things the same (i.e. powder brand, powder charge, primer, bullet brand and size, etc.) This is my whitetail hunting gun.

I tried PMC 230gr. FMJ in all 5 of my 1911 pistols. It was not like the brass in the afore mentioned paragraph. :( 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. :what:

I have tried their ammunition in other calibers and the inconsistiency seems to show up there as well. Accuracy is only decent.

I have never experienced this when using Winchester White Box or Mag Tech 230gr. FMJ.

When I tried PMC ammo at an indoor range, it appeared the flash suppressant wasn't as effective as other brands.

Of the popular priced 230gr FMJ, I've found American Eagle to be the most accurate. I now buy 5-700 rounds at a time from the local dealer for cash to get the best deal - better than online.

I've used both the MagTech and S&B ammo and don't have any complaints about either. Both reload well, although the primer pockets are a little tight in the S&B.

I've probably shot more PMC 45 than all others(factory ammo) combined, and my experiences have been just the opposite of bigmike's. I'd estimate the count to be in the neighborhood of 100,000 rounds, give or take a case. Never had a misfire, and only one squib...recently...that still had enough punch to knock a falling plate over and cycle the slide with a 16-pound spring. The report and recoil from that one round were noticeably lighter than the others, but that was it.

Mike...How long ago did you have the misfires and do you know the lot number? Curious to know if it was the same as the one that I had my squib with. The rest of the ammo in that lot...2 cases worth...have been okay.

Standin' by...
