Nice, I just loaded 300 new starline cases with 300 gr Cast Performance WFNGC bullets to an easy, comfortable and accurate 1255 fps with 4227 powder, burns clean at those pressures, don't know what it wouldn't handily dispatch either.
Gunner: I'm loading the following that worked well in my Ruger 454 (since traded
)
Starline brass
WSR primer
27.5gr H-110
Cast Performance 325gr LFNPD hard cast
1340 fps
Heve not tried it on this gun however
