PMC shot fine in my Glock 21, but just
wouldn't get along w/my Wilson 1911, the
KZ45. Wilson said that the PMC fmj's just
didn't have the right overall length and
could cause jams. Wilson doesn't guarantee
reliability with PMC.
I needed a few boxes of ammo fast a couple weeks ago and wound up with some 230 grn PMC. It cycled perfectly through my S70 Gov'mnt and had all the accuracy I needed (keeping in mind I went through all of it while shooting at 7 yards).
Clean-up was a bit of a chore; the feed ramp had a particulary stubborn spot but some extra elbow grease applied via a toothbrush eventually got it off.
Push comes to shove, I prefer the S&B I usually get but wouldn't shy away from PMC in a pinch.
I personally prefer WinClean ammo, but the PMC seems decent for my Kimber Govt. I haven't noticed any extra cleaning necessary, but even if I go and shoot one mag full I'll come home and clean my guns. (some call me anal, I call it maintenance)
My Wilson Protector doesn't like PMC ball very much, either. Seems to FTF every now & then. Of course, it could be the two old Wilson magazines I had, too - one of which self-destructed when I snapped it into the gun during a reload at an IDPA match. Seems the plastic base pad lips snapped off. Guess i'll go with the metal basepads.
