I finally got a decent selection of pellets in to try. No photos so you'll have to take my word.
The stock barrel at 25' (that's the most I can get out of the basement at present), 60F ambient, 4 shots per group (the valve was modified and I only get about 32 shots per CO2 car), and the following three pellets:
RWS Hobbies- The Mark I really likes these pellets. 1" CtC with two shots stacked on top one another.
H&N Sport- A hard hitter. Grouped a little over an inch.
And the big suprise of the test......
Crosman Field Hunting pellets- Held a 1 inch group! The spread was a little more open than the Hobbies but satisfactory. I feel more comfortable now and will take the Mark I in to the field for Fall squirrel... hey, maybe even rabbit if I can get close enough!
at the connecticut airgun show --- nice guns ---- is yours stock --- my seems pretty accurate so far ,need more .22 cal pellets
TOO many freaks and NOT enough circuses edit --- brain fart
