I,would like to know how to compare lup to psi if possible. Also,do the numbers have any berring on recoil ? I'm Trying to find a load for caps around 1200 fps that is not at the high end of recoil. I'm now shooting from 26 and it seems like the shot takes forever to reach the target. 17.9 grains clays,waa12 wad, win-209 primer and AA hulls. Is the (time to break) just a head game or would a faster load help? Hope someone can help me out. Thanks, Mike K.
