I have a vintage Winchester 94 in 38-55. I have a box of 255 grain hard lead RNFP boolits, sized .379 (the bore slugged .378). I have a variety of powders in my magazine to choose from - IMR mostly, and a couple of others (Varget for one) so would like any info/experience with this cartridge - I intend to use it for deer hunting, so plinker loads are out, but would also like to stay away from full throttle loads to be nice to this gun. The boolits are PB (no GC), so I am thinking loads in the 1200-1500 fps range perhaps? I hav an abundance of 3031, 4350, 4895, 4064, 748, 4227, 231 (and a couple of others that escape my brain at the moment)...
Any help/advice appreciated!!
