Hawk 1
Seyfried's best results were with Lyman #457-121P. Same mold for both the Parker-Hale and Whitworth. He had both molds, the traditional hex mold came as an extra cost item sold with the rifle. I had one, cast Bhn 8 soft bullets in the Lyman BUT, I did use the hex wadcutter that came with the rifle for over-powder wads. It did everything it was reputed to do on 600 yard steel...but the recoil was brutal, and after the initial joy making hits with a muzzlestuffer at medium range I traded it off. The recoil was just not fun.
