FX Impact M3 question?

i think .177 - .30 are all the same but i believe once you get the .35 it's heavier.
Ok this is what I was thinking. Thank you much. I have a 25 600mm and am trying to figure if the reg pressure for 33.95 heavies will be close for a 30 cal 700mm barrel kit. If the same hammer weights I think it will as the factory 700 mm 30 tune is 100 bar 2nd reg. I’m currently running 105 with 33.95. Should be close with just a swap. Thanks man.
