I have a impact mk2 .25cal with just a probe and tp modification, on max it’s shooting nsa 36.2 slugs @915fps and jsb 34gr @ 945fps. Now with that being said to have the same poi from 50-75-100yds, the power wheel is on max for slugs and power 5 for jsb34gr. Also I shoot jsb .25gr @890fps on power 2, and 860fps on power 1 all with very consistent speed. So my question is will be able to do the same thing with the power plenum but with better efficiency? Thanks
