I was shooting MKIIs at 960 fps from the pellet liner. I tried ten Hybrids for fun, and they were at about 1060 fps, with very close spread. After installing the .25/700 Superior liner, velocity dropped by about 40 fps for the MKIIs and the Hybrids. After attempting to retune to previous speeds, the best I could do was 950's for the MKIIs and 1040 for the Hybrids. This is as high as I could go. Hammerspring is maxed, reg is at 145 bar, valve adjuster is fully open. If I raise the reg, velocity actually drops.
I'm wondering what other people are getting for max velocities with the .25/700mm Superior liner? It seems that the Superior must be a little tighter than the pellet liner to slow things down like that.
My Impact was ordered 1/8/20, setup on 1/10/20 by Utah Airguns. It should have the original longer hammer spring, not the shorter one the later Power Plenums come with. I'm not sure why I can't go over 145 bar on the reg, I know people are going higher than that. Any thoughts welcome. Thanks.
