How does that compare to your stock barrel, numbers wise? Obviously good lol.This is amazing 110 bar pw max 50 gr jsb 875 fps 85 fpe! And to think it was pushing 9 fpe more at i forget 150-165 bar pressure with pellets! If i had some heavier slugs i think i could go over 100 fpe but im not going to try
