I just picked up a pound from my guy with a component-stuffed-closet in his radiator shop. He had quite a bit.

Been putting together loads for my Springfield w/ 165s. Gonna try some 215 SGKs through my 338-06, and would like to see what it can do in my 257 AI w/ 100s, as I get 3320 fps from IMR-4350.

Interesting stuff indeed!
