Have an early reproduction 86 Winchester/Miroku over at Turnbull Mfg Co being rechambered to 45-90.
I currently have Tom at accurate molds making me a LBT style LFNGC mold that should drop at 400 grains or so.
Going to limit the maximum velocity to under 2,000fps.
My question is what alloy should I use for casting?
Any guidance is really appreciated.
Tom
