Returned to the range today, after finding a Wal-Mart some distance away that did have Winchester 115g fmj. Picked up a couple hundred rounds. Took 100 rounds and set up targets at 10 yards. Used only the slide catch release to load the 1st round of each clip. This time I had no failures from any of the 1st rounds... but... Had 3 failures out of the 100. Two failures, from the middle of 2 different magazines, I felt and heard the trigger click, but nothing... the firing pin did not fire. No dents in either round's primer. After reloading each of those rounds, they both fired. The 3rd failure also occurred in the middle of the magazine, so it also had nothing to do with my operation of the slide. Trigger clicked, nothing. Ejected the round and there was a slight dent in the middle of the primer. From my observation not as "strong" a dent as the spent cartridges I compared it with. After the failures yesterday with the Sellier rounds, I'm beginning to wonder. So, I'm wondering if there may in fact be a problem with the Steyr? Gunk from the long storage in Texas I've read about? Possibility of any error on my part? I'll clean and lube it again per DAIadvisor's guide, and I'm thinking I'll run thru another 100 sometime this weekend and see if I get any more failures. If so, I expect I'll be sending it to Steyr to check it out, unless you guys have any thoughts or suggestions or are pretty sure this is still operator-error. And I don't feel at all competent to try and disassemble the trigger assembly for cleaning. Thanks ahead of time.
