I've been a fan ever since I was a kid and I saw the black and white photo of H. Guy, (pronounce Gee, hard g long ee), Loverin wearing a suit and tie in an Ideal cast bullet loading manual. The black and white renderings of the bullets and the comments solicited from ordinary bullet casters about their pet loads and their uses.
All of those grooves just begging for a dose of that black Lyman lube and fit with a brass colored gas check. Gently bent in a Lyman/Ideal #45 lubri-sizer, and launched, under size, at .308" down the barrel of your sporterized Springfield. Ahhhhh, the innocent days of my youth.
