I bought my M9-A1 about a month ago at Cabela's, and it's one of the PW-imported "mutts". So far, I've only had it to the range twice, and have put around 200-300 rounds through it to see what ammo I can comfortably share between the Steyr and my Beretta PX4. So far, neither gun seems to be as accurate with Sellier & Bellot as with other brands, although the S&B (incl. Herter's 115gr made by S&B) didn't have any issues aside from inconsistent accuracy. Up to this point I've had two FTFs (Aguila 124gr FMJ and Federal or Remington 115gr JHP) and one FTE (Speer Lawman 115gr FMJ), and my much more experienced shooting buddies assure me that this isn't unusual. One, who was there when I had the FTE (and reloads his own 9mm), thought that the Speer casing looked "off" and chalked it up to an ammo issue rather than the gun, and said that he considers 500 rounds as the minimum break-in period. Furthermore, he shot the Steyr and loved it, which I take as high praise coming from a competition shooter with quite a collection of high-end firearms. Anyway, my first thought after reading various posts about M9 issues was to panic a bit, but thinking back to other guns I own/owned, two FTFs and one FTE during the first ~300 rounds is normal or even on the low side. But being new to Steyrs and otherwise loving this gun, I guess I'm curious as to what is reasonable for break-in.
