I don't cast in diameters smaller than 35, and have more molds in 35 than any other caliber, so I guess I must agree I assume you're talking rifles? 200-250 gr of .358" lead at 1800-2000+ fps may not be a death ray, but it'll put venison on the ground.
That said IMHO 45 caliber seems to be where cast lead seems to pull even with jacketed bullets.
