My Cz 455 shoots tnt and 20g game points very well, but won't shoot the polymer tip ammo for squat. I haven't tried the remington but it's all made by cci so don't know if I will try it or not. I have never measured the groups but it's the size of a nickel at 100 consistent. The 22lr barrel shoots lights out with every ammo I have tried except bulk packs and mini mag 36g.
