Yeah...but I wont need to. What happens in real life is not same as what happens once and gets turned into internet hype
Well, what concerns me is the excessive pressures. I prefer to run well within the range of pressure set forth by the engineers who designed the guns, because I've owned a few guns that had been run with 9mm+p+ ammo, and their frames started cracking along with the barrel link pin bending, and other issues.
So I DO have some experience with guns run with excessive pressure, and the stuff listed in the article sounds about right - locking lugs cracking, bolts breaking, gas ports getting eroded, extractors breaking, reduced barrel life (although that's more subjective, but certainly throat erosion). Not to mention needing updated mags to avoid the feeding problems from the slightly longer OAL. It's just a lot of extra wear for not a lot of return on that investment.
But you do you. There'll be more M855 around for me to use since you'll be using up ALL of the 855A1 with all that shooting you do...
