I had an A-22 for a couple years and when I put a Gunshack trigger-spring into it I was able to get groups under 1" at 50 and about 1.5" at 100, using a 12X scope and SV ammo. The t-spring got the pull down to about 2.5# - half of where it started. As for ammo, you have to test to find the 'best' for your particular rifle. Mine did well with SK+ but also CCI-SV. Having a good 'Stable' rest is key to 'real accuracy'. I moved on to CZs after the A-22 - you can get a used CZ452 or 455 for the price of an A22. But I also have a B-22 that I've kept since b4 the 'A' and it shoots almost as well as the 455 I have. And ALL my 22s have 'low-pull' triggers after 'polishing the innerds' and adjustiing or replacing springs.
