OK to use?
I think they had a couple bad batches a couple years back but I haven't heard anything bad about them since then.
Think about this though...The difference between Wolf primers and Winchester primers is $10.00 or less...That's 1 cent or less per loaded round. There are some things I just don't think are worth skimping on.
I had two CCI primers FTF on me, too, but that doesn't make me write off CCI. I'm fairly sure it was the reloader (that'd be me) not fully seating the primer. That's probably the case with most FTF's.
The Russian primers are as good as any of 'em, for less money, and I haven't had one fail on me yet. I'll take 'em. :-)
Note: due to the slightly thicker cup on them (again, similar to CCI's), if you have a featherweight "race trigger" on your gun like some folks have, the primer strike might be a bit light to set it off the first time. If you're a competitor with a race trigger, I'd suggest using Federal primers for their thin cups. Stock triggers should be fine if the reloader has done his part.
