If memory is correct in the fall squirrel season of 1964 I was introduced to Standard Velocity .22 LRs. Prior to that, I had not even known they existed. After trying them I never looked back & have shot almost nothing since. The Squirrels simply do not pay as much attention to one of them going off as they do to the Sonic Crack of a Hi-Vel .22 LR. Never found them lacking in killing power if one shoots straight. Once rolled over two young groundhogs with one shot, I thought I was shooting at one didn't see the one behind him. Also knocked out a few coons which showed before dark while squirrel hunting with them.

I was never a really good pistol shot but did kill some squirrels with a Roger Mark 1 as well as a groundhog or so with it. The problem there was simply one of shoot-ability.
