td0g, I have the A & B22s with 5-6 of the 10-round mags and 2x 25rnd. They all are interchangeable and work fine in Both rifles. For the 10s I un-wound the mag spring a bit to lighten the tension to make loading easier, still cycles just fine. And the 25 has a slide-button to simplify loading. I get MOA with the B and close with the A, after working the triggers to around 2#. The A won't cycle properly if I go lower, but the B is down to 1.4# right now, even with the Safety blade intact.
I have an A17 and I am very impressed with the accuracy at 100 yards. Shoots as well as my CZ Varmint. Also agree about the Butler Creek 25 rounders with the thumb slide. Excellent design.
I have a heavy bbl 10/22 and its a favorite of mine. Green Mountain barrel. I find that when I take it to the range to shoot groups, the first couple of shots are a little off, and then it tightens right up. Must be something to do with the barrel residue.
