i have a mosin and its a shooter! its a 1943 Tula LONG barrel and with .312 j words it shoots 5/8 to 3/4 in at 100 yards. Now since it has a mint bore and fine crown. I want to make a cast shooter out of it.(slugs@ .3125 now the catch most load down for easy low recoil match loads(200 yrds and under) I want to go the opposite way i need full power cast loads to ring steel with @ 200 400 600 and 800 yards.... what i have lee c312-185-2r and c312-160 both cast around .315 i have a 314 push thru sizer. planning on TAC-1 lube with gaschecks and my alloy is COWW sweetened with 1% lino now can i air cool them? or do I need to waterdrop? or bake at 465 degrees and quench? and then there is load data i was thinking of working up higher end loads with 4831, 4895, 4350 or 5744 and no fillers? has any one done anything like this? or is there any other mold i should look at?
thanks gutpile
