I started out with a Lyman mold # 457102, 445 grains, gas checked sized .459, there about. I've use Alox or what ever lube I could find.then settled on LBT Blue. I've used most any alloy, wheel seems to be the most common. Then I found a mold throwing, maybe NEI, 350 grain gas checked when I Decided I was not going to run into any Cape Buffalos or American Bison here in Virginia. I've found that IMR 4064 and IMR 3031 do well for full power loads. When you fire a hundred rounds of 445 grsbullets in an after noon,you have done a days work.
