My favorite target load is 10ga cheddite hull cut down to 2 7/8", cheddite cx2000 primer, red dot powder, remington sp10 with four 1/8" nitro cards in the base of the wad 1 1/8oz shot, star crimp. The load can be found on the Parker site topic reloading the short 10. 7600psi and 1150fps. Nice mild load for the old guns.
