Lots of folks used to use the .375 Winchester brass necked down for both the 30-30 and the 30-30 Ackley. They can be hard to find now. I saw my uncle raise up his pre-64 Mod 94 and shoot, off hand, at a big doe a tad over 300 steps. She dropped like a rock from a high shoulder shot. It was her unlucky day! ha
