Interesting find in the reloading stash this week. I think these might be the lightest .30 caliber bullets I've seen, and certainly lighter than anything I've ever loaded or shot in the past with 308 Winchester, 7.62x39, 30-06 Springfield, or 308 Norma Magnum. Reloading data on the Internet seems to be pretty sparse; the smallest .30 caliber bullet I can find data for is 100 gr. I'd be curious to know if any other members have loaded a bullet this light in a .30 caliber rifle.
