Mike wrote my #'s on the box but i burned the box ..in .177 cal. the high was like 840 i think with silver bears and he also tested some heavier pellet's also i don't think anything was below 800 i think like 804 was the lows on a certain pellet he tested ....Mike does a nice job on the guns he tunes very pleasant shooting ....
enjoy your new gun ...
