Been working my way through the JSB pellet sampler and while some are better than others, honestly they were all pretty OK until I got to the Diabolo Exact Monster 13.43 gr. First shot was about 5" low at 17 yards. I thought I'd try seating the pellet further and see if that helps. Nope, completely off my target ~8" low. I didn't see the point in continuing any further with those.
Interestingly, the Diabolo Exact Heavy 10.34 gr was a decent performer and makes a nice group (at least at this distance). So that probably represents the ceiling for pellet weight in this particular rifle.
