[QUOTE="jarnold37, post: 1754442, member: 29241"] There may be more to this that can be brought out. A local gunsmith told me an episode where a local hunter brought his rifle to him to find out why his bullets were sometimes key holing and occasionally not even hitting the target at 100 yds. Upon inspection the rifle appeared to be in pristine condition, on the outside. After looking inside the bore it was obvious. It had never been cleaned and was severely pitted with scabs of rust. With the rotational velocity of a 140grn bullet with 9 1/4" twist, spinning at over 241,000 rpms, that has had its jacket melted and gouged will possibly come apart in mid flight. On the other hand, on a deer permit, I experimented with a very small bullet going very fast, but using a lapped barrel. I chambered a barrel in 30-378 and loaded Speer TNT 125 grn bullets at 4050 fps. Shots were from 88 yards to 488 yards and was the damage was basically the same in each deer. None took even one step. Obviously these bullets were intact until they hit. Even though it started fragmenting on impact it kept on making a wound that was fist sized clear to the other side and hemorrhaged the off side drastically. I remember an experiment where they shot steel plate with a 22 diameter bullet. As they increased the velocity the "mark" on the plate increased in size and at very high velocity it actually put a hole through the steel plate. Something to consider [/QUOTE]
