I have lots of brass to fire form; I’ve seen it mentioned that some use unique in the 7-30 waters with cast loads; I.e. the load as in 10 grains unique. I know for plinking loads in 30-30 the parent case Ive had very good luck; I don’t see this in the Lyman manual or any other source I’ve looked at. I figured I’d start at 8 grains of unique and work up . Boolit by far he way is the lee soupcan 7mm. Anyone using this or has in the past? For jword loads I’ve had good luck using 4895 and Varget. I figured for fire forming I could play with a lighter load and hopefully find a woodchuck/raccoon/ coyote load while I was at it. I have an excess of unique right now and would like to avoid buying a new powder this instant until all our bills from having a baby and remodeling half the house are taken care of, or actually our saving recouped as we pay as we go.
