My .177" Mk3 TX200 HC has no problems with Crosman Premiers.
I know I'm far from the world's greatest shot (barely had the rifle 5 weeks), but I still pulled off a group that was 1/2" (by a hair) at 20 yards (outdoors) using them from prone - took me a while though, there must have been whole minutes between some shots.
My daystate X2 (which is 4yrs old) loves either jsb exacts or daystate ft select in 4.53

All of us could take a lesson from the weather. It pays no attention to criticism.
