Two for one tunes, I've been wanting to tune my M3 for JSB monsters 25.39 and had time today, so I raise the reg and set the adjustments to shoot them @920fps then backed the Macro from 16 to 4 and the 18.13s are shooting 890fps. both are getting good groups considering the wind is howling today 12-20 variable from around 4oclock position from my shooting table. Heres my groups @ 40y. Blues are 18s greens are 25s and yellows are a sighter. About 6shots in each group more or less

This was always the most impressive thing about the impact platform to me. I did the same with the .25 I had. Set it to run the 33.95 just over 900 and could still shoot the 25.39 with a decent extreme spread in the same velocity range by just turning down the macro. Neither my Maverick or wildcat bt could reproduce that.
