Lyman’s cast bullet manual has Bullseye powder loadings for many Lyman bullets, notably, 358477, 358156GC and 358429 Keith.
They get some nice mid range velocity loads (1,000-1,100 fps) using these bullets with Bullseye.
I’ve never used Bullseye in 357 Mag mid range loadings. Has anyone out there used Bullseye and cast bullets of 150 gr to 170 grs? Any suggestions on experiences is greatly appreciated.
