I think any negatives you're reading here, are the shooters, NOT the gun. My bnib Sport II OR, with CT Red Dot, shoots bulk 55gr stuff, under 1" ALL day at 50yds, no matter how many shots the group is, just a shot out center target, and my gun's not even settled in yet. My ammo is mixed stuff, not even same brand. I'm pretty sure when I scope it, use the same brand ammo for sight in at 100yds, I'll be looking at the same shot out center target. The heavy bbl profile helps immensely.
