Now that it is broken in, I spent some time at the range today getting some 2 inch groups @ 100 meters(+-330ft) with bulk .22lr Winchester 40gr. Is that standard?

Should it be better with bulk ammo or i'm in the "ballpark" and better results will come with better ammo now?

Just making sure it's shooting like it's supposed to. If it aint broken, I wont try to fix it ;D

Regardless, I love shooting the damn thing, clays have no chance at that distance, same for the left-over pieces scattered around. I have not enjoyed shooting a rimfire like that in a long time.
