I have just purchased a few cases of Remington RXP Target loads from an old shooter. I also have about 2500 RXP 12 gauge wads. I also have an endless supply of 700X powder. The only loading data I can find is on the cartridge box. Data calls for DuPont 700 X and 97* or 209 Target Primers. Regular 209 primers fit, but the primers that were in the RXP hull are significantly shorter. Regular 209s protrude past the base wad on the inside. Has anyone had experience loading these RXP Hulls.
