When I was shooting the Polish at 100 yesterday, there were some guys shooting pistols down at the 25 yd range. The range officer came down to me and said, "Well don't shoot any Silver Bear ammo in your Makarov, we just had one blow!" I told him, heck I shoot Silver Bear all the time in mine, what happened? He said there must have been an "overload" or something, there was a LOUD boom, the slide flew right off and the barrel is bulged badly. I asked what kind of "Makarov" and he said he didn't know, thought it was Russian. I needed a break so I walked over. It was a commercial FEG Hungarian PA-63, in 9x18 Mak, with an aluminum frame, NOT a "real" Makarov. There was a NOTICEBLE bulge just in FRONT of the chamber, but there was NO visible damage to the frame, or chamber, or even to the peice of cast aluminum holding the barrel around the chamber! There was also no visible damage to the slide, inside or out. The guy said he had shot almost the whole box, this was the last mag of the SIlver Bear, and was just about to switch over to some Wolf ammo when it blew. I asked him if there was ANY chance he had "stuck" a bullet in the bore before he fired, and he assured me he didn't, all holes had appeared in the target when he fired, he said. (I looked down the barrel, and you couldn't even see any damage or the bulge, from the INSIDE.) I thought MAYBE it had fired before it went into battery, but USUALLY there is a lot of visible damage, right? ESPECIALLY to that "light" cast aluminum frame! I SHOULD have at least seen a CRACK in the frame, or the light casting the barrel was pinned to. Plus I saw the case, just a couple of small cracks around the mouth, NO bulging or cracks at the base. The "Heavy Load" doesn't wash either....wouldn't the CHAMBER have blown, or bulged? NOT about 1/2" in FRONT of the chamber, right? IF in the CHAMBER, the casting HOLDING the barrel would have at least cracked too...PLUS more damage to the CASE. I STILL wonder if maybe he HAD stuck one becasue of a LIGHT load or one with no powder that still jacked the slide....and pushed the bullet an inch or so out of the chamber into the barrel, and was pushed out by the bullet that fired and blew it. I never thought to ask him if he had any other malfunctions, or if this was the FIRST shot of a new mag, DARN. While I never owned or shot a PA-63, I remember BobinStLouis used one as his carry gun, and many guys have had good luck with theirs. After holding that LIGHT and cheesy aluminum frame in my hand, though I'm not so sure I would ever buy one. It was 95 gr FMJ Siver Bear they were shooting, I've shot a couple of boxes of it through my Makarovs, both all steel, both the EG and the Russian Commercial Baikal I have now Now I usually either shoot the cheap Russian steel cased 95 gr, FMJs or the Brown Bear 115 JHPs. What do you think happened?
