Well, that wasn't the problem...

So, if you'll recall my misadventures with the Steyr C9-A1 and the Wolf Polyformance 115gr FMJ ammo...

I stopped by the Steyr booth at the show. I mentioned to the guys in the booth that I'd been shooting one and asked if there was an updated extractor available for the gun. He allowed as there was, and I said that was a good thing, because mine's been a complete dumpster fire so far.

He also told me about the Steyr's tight European tolerances and how I should avoid weak ammunition because a finely crafted piece like the C9 would be a fussier eater than...other guns. I think I did a good job of keeping a straight face, but you'll have to ask Kevin if I really did or not.

Canis lupus lupus, the Steyr's bĂȘte noire
So, anyway, from the wild ejection pattern of the Wolf and the number of malfs, I had surmised on that previous range session that the Wolf was extremely variable in velocity, with weak rounds failing to run the gun and hot ones functioning it fine. I saved ten rounds to take to the range and test over the chrono...

Here are the results:
Wolf Polyformance 115gr FMJ
LO: 1150
HI: 1178
AV: 1159
ES: 28.56
SD: 9.74
That's...well, pretty much the opposite of inconsistent. As a matter of fact, it borders on freakishly consistent for cheap FMJ ammo. I think it's safe to say that the problems are with the Steyr, hopefully they can be solved by an upgraded extractor, because otherwise this thing is just way too annoyingly fussy for me to bother with. If I take a pistol to the range, I want to be able to buy whatever cheap range fodder they have there without worrying whether my gun will run it or not.

At least the ten-round chrono string went off without a malfunction.

This makes 630 rounds fired through the Steyr C9-A1 without cleaning or lubing, with five failures-to-fire (#8, #472, #535, #555, #558), seven failures to extract (#234, #266, #276, #531, #535, #543, #558), and one failure to go completely into battery (#116). 1,370 rounds left to go.
