I've never shot at 200 with a muzzy, only out to 120 or so. But for me, at 100 yards 2" groups (3 shots) is acceptable. My experience is that shot group sizes with muzzys can vary a lot from day to day (different powder charges, weather conditions, wind, the shooter - me- , etc.). I would prefer a muzzy that consistently, every day shoots around 2" groups, than a muzzy that one day shoots 1" groups, and the next day 4" groups.

I have shot 1" groups with a muzzy at 100 yards, but only a few times. Usually my groups are in the 1.5" - 2.5" range. And that is basically acceptable for me, although of course I would like to see better .
