I have shot many deer with 240s, mostly JSP's. I don't know or worry about speed as I dont have a chrono, but my load is 46gr of 4198,it produces 1.125 groups, and I think it is 2250-2300 fps. Most of the bullets get clean pass through, but on quartering shots I have sometimes recovered slugs under the offside hide, they were picture book mushrooms. That on 130-150 pound deer here in Mo. @ ranges from 40 to 220 yards.
