I don't care for shooting .22 Mags out of a revolver. I've had several convertable sa revolvers. The first a beautiful little Colt New Frontier .22.
No body, and I mean no body cautioned me about the severe muzzel blast that round produces from a hand gun. After 6 rounds I was deaf. Litterally deaf. I ended up with a vicious screaming headache that made me ill. Eventually the deafness left and at the tender age of 21 I had a full blown case of nerve damage caused tinitus.
This was in the early mid 70's. There just wasn't the emphasis on ear protection then as there is now.
That was the beginning of my hearing damage. Next I tried ear plugs. Sonic Earvalv types. Didn't help much. Eventually I found out about ear muffs.
But the damage was done.
As far as accuracy I've never tried to wring the most out the mag round. Because, I found the archaic old .22 WRF round. Same case as the mag, just a bit shorter, uses a lead bullet the same diameter as the mag, but is much more accurate in every revolver I've used it in.
CCI is the only maker now, and their stuff is toned down a wee bit. But it is still more accurate in my current OM Super Single Six than any of the magnum rounds.
