Fellas Im a newb caster looking to set up for 480 ruger in a mauser bolt action. After low speeds, around 800-1000fps, whatever mixes work. Things are getting a bit scarce where I am but I found the Lee double cavity 400-476-RF mold and the RCBS lubamatic sizer die in .476. Bore is around .474. Does this all sound okay to make a start with? Where do i find a top punch to match this bullet?
