500 smith and load it with longshot powder. Midrange loads that essentially just equal or beat the 500 jrh/500we and with the 500 smith ya get sucha better pick of bullets. If recoil is a problem (which it def can be on the single shots without a mizzle break) the 480 ruger makes sense. Ive found that itll easily match the 475 linebaugh velocities in a revolver when shot out of a single shot as stated above. With hornadys support of the round ive found brass is readily available
