I haven't done much testing from a rest at 25 yards with mine. It will keep all 10 or 18 rounds (depending on mags) in a 5 inch circle target at 25 yards without using a rest. And it is minute of clay bird out to 50 yards. I mostly use CCI Standard, CCI Mini Mags, Federal Champion 510, and lately Aquila Super Extra.With the original question being what ammo does your 44 like best, I expected to see a few 25 yard rested group sizes. All of the above posts relate to the pistol simply cycling. Has anyone shot a group less than 3" with any brand?
