I shoot mine standing with a hacked off hammer spur with the comp removed DAO (the comp is useless).
And a red dot. At 25 yards easily. All in the 10 or 9 ring .
It shoots cheap ammo. WWB 115gr FMJ. Blazer brass 115gr FMJ. My homemade 124gr xtreme plated. And those are .355s or .356..
I dont shoot lead. Did shoot Bayou Bullets 124gr PC. They shot well.
I look for cheap new ammo to shoot in it, just to see what it wont like. Ammo IMO wasn't an issue.
