I had a friend stop by the shop tonight and return a box of the 220 rnfp loads that I made up for his Krag. These were loaded with 4895 and were coming out the muzzle about 1950 fps, a pretty standard hunting load for the Krag. The fellow handed the loads to me and said he wasn't going to use any more of them he was going back to a 150 gr. jacked bullet. I asked him why and he said that last year he filled his and his son's permits with one shot and that that load was just to powerfull for deer. He shot into a doe at 110 yards and the bullet went through the front shoulder of the first deer and broke the spine of the deer standing behind. He recovered the bullet and it was nicely mushroomed about 50 caliber and weighed about 180 grains. Other than a finisher for the deer shot through the shoulder that was still flopping the one bullet killed two deer. This is the same bullet I am working with in 30-06 this year.
So, warning cast bullets are too much for deer.
