I have an American Compact in 22 and a full size American in 17 HMR. The 17 averages just under an inch at 100 yards. I also have a Volquartsen in 17 that does .5" at that distance. Of course they both faver different 17 loads.
My Compact 22 constantly shoots .4 to .5" at 50 yards. It does this with Eley Match, Target, and Edge. SK Flat Nose shoots the same and this is what I use for squirrel hunting. CCI Mini Mag HP's do almost as well, usually shooting under .75".
The American 17 has a Tract 3-9x40 scope and the 22 usually has a Burris 2-7, but I just recently put a Cabela's 4-12x40 on it'
