A few months ago I posted some pictures ofan old Remington-Lee rifle that I inherited. The gun is chambered in 30-40 Krag. The original loading was 30-40-220 (30cal, 40 gr. smokeless powder, 220 gr. bullet). So I loaded 220gr. Sierra RN's on 40 gr. of H4350. Maybe 1800fps. Got a 75 yard shot at a deer. Deer took a couple of steps, fell over. When I was skinning, I was kind of surprised at how little damage there was. Hole going in, slightly bigger hole coming out. Oh yeah, a hole about the size of a nickle through the top of his heart. Compared to the damage I'm used to with a 100gr, 25cal moving 3100 fps it was quite a difference.
