You need to look around for a cramer #50 mold. They cast a bullet that was designed for the 30 carbine. The cramer mold I have casts a sp and a hp gas checked bullet.
They are an accurate bullet, playing around @ 50yds with a 308, a 10-shot group
Those hp's really put the smack on anything they hit. I cast them out of nothing more than range scrap (8/9bhn).
