It's interesting to see the variance in groups people are mentioning.
22's are always finicky, but after seeing this thread, I decided to get out some TAC22 I'd bought a while back to see what it would do in several of my rifles.
At the time I bought it, I'd seen lots of positive posts about it, so when I'd found it on sale, I'd stocked up.
When I got it, I tried it in a few rifles but wasn't impressed, so it went to the back of the safe.
I ran it through a few the other day and had moments of greatness only to be ruined by huge swings, as much as 2 Mils at 50 yards. It won't win any prizes in the matches I shoot, but it will be fine for playing around.
I do believe it will be good for handguns too.
