It's a sad sad day for the mikejk household. Purchased a grab bag of steel cased ammunition from a guy locally a week or so ago. There was what appeared to be Silver Bear HP in a zip lock bag. Being as I have never tried the stuff I hit up the range. First magazine good. Second magazine good, good, good, nothing. No click, nothing. I dropped the mag and ejected the round in the chamber. Then pulled the trigger, click. Short Stroke. Son-of-a. No longer 100%. I did finish off the rest of it w/o an issue. We're still looking at 2k+ rounds of steel and around 1k brass w/ 1 malfunction. Looks like I'll have to swap out the ST-T2 when shooting that stuff.
