any one else have a problem with pmc out of 7 inch barrel pistol ?
Went to range yesterday and it ran ok but it started pouring rain so I only got 1 mag thru it .
went back today and was traded some pmc for some ar parts , this crap was short stroking every round so I pulled it down cleaned chamber and oil the heck out of it and it ran better but not 100 percent .
I changed to federal 556 xm193 and it ran great for 3 mags no problem .
wondering if its just new chamber and will break in and run pmc or if pmc is just to light for 7 inch barrel ?

PMC Bronze is a bit under powered. After break in with a carbine buffer you should be fine.

I'm running an h2 and it was pmc bronze

I've used a lot of PMC Bronze in 7.5" and 8.5" PSA pistols with 0 problems.  Even swapped the carbine buffers for 9mm buffers and they still ran 100%.  I know that doesn't help you any, just sharing my experience.

pmc bronze is also a known good plinking ammo in all of mine too. i have everything from a dpms kitty kat (7.5" barrel) to 20 barrels with different buffer weights. shoot 100 rounds of 5.56 and try again.

I'm out of pmc and probably will not buy or trade for any more , it runs 556 fine I have few hundred rounds thru it now
