That is a fine group, but is a far cry from .2" group....A dime ' s diameter is .7".
It generally takes a dedicated bench gun and much better ammo to semi-consistently shoot .2 groups.....I have seen a lot of .2 groups but have never, ever met a man and a gun that could do it all the time. If the wind doesn't get you, that one flyer in a box of even the best ammo will.
Very true. Probably never as consistent as a bench gun. But really good enough for sling and scope.
For silhouette, I'm shooting standing unsupported with irons, and with results as Iit is..... If I miss, it's all me.
