I can agree with that. Crushing would play a part, but at 300 WM velocities tearing from the temporary cavity would play a bigger part in the trauma. I'm not the most articulate person while typing.
I think they were at one point. One of their members tried to come on there and go off topic. It's amazing that people won't consider the terminal performance of the TMK's.
4 posts in and there was 25-06 and a 90 grain Hammer mentioned...
I've heard in other places the Hornady 55SP works really well, have never used on on game though myself. Impressive how well it holds up to even Swift velocity.
Thanks for sharing. I have a win pre-64 220 swift, but it’s got a slow twist. Was looking at these, the Sierra 55gr game king #1365, or the 55gr gold dot. Figured I would get about 3800fps out of it. Have you used any other or just the hornady bullet?
They are a sweet little bullet. They act a lot more like a bonded bullet than you'd expect. Hornady does make a SP SX which is supposed to be much more explosive. I dont buy them though so unsure of the real difference.
I haven't tried the Gameking or the Gold dots (yet!) but they are both on my list. an acquaintance has urged me to try 55 grain Nosler ballistic tips after having used it on deer with good results so thats the next experiment.

I read that book shortly after I bought my swift completely unknowing that he had used one. I was thrilled when I read about his use and love for it. Now just think how much bullets and powder have improved since then...
I havent tried anything over 55 grains yet but there is quite a few compelling bullets I'd like to try in that 60-69 gr range. 60 grain SP, partition, gamekings and this Nosler.Berger's calculator shows them to be marginally stable in a 14 twist, but I bet those would be pretty sweet at 220 Swift speeds!Nosler Bonded Performance 64 Grain Solid Base bullets

I estimate this deer at 110# live weight. I shot it 1 hour before I left for work, so the autopsy of soft tissue regarding lungs etc. Will have to be verbal. I noted significant blood in the chest cavity upon splitting the sternum. The path through the lung tissue was roughly 1.25-1.5" across. No fragmentation was noted. The damage to the liver was roughly the size of a nickel. Due to the frontal nature of the shot (the deer was very nearly facing me dead on, albeit with his left shoulder and rear him slightly toward me, the projectile's path through the vitals was not as "text book" as a broadside shot which somewhat limits our ability to ascertain its terminal disruption. However, the projectile seems to have a deep and more narrow wound path with sharp demarcation which indicates good velocity through the target as well as sharp edges, as opposed to a round like the RA556B or similar which adopt a more "blob" shape.) The projectile did not seem to directly impact the spine but did pass very near. He immediately locked up and went down and did not move again. Blood at the site was minimal and mainly from his nose/mouth. The rest of the pertinent data follows in a video I will upload.
Weapon: 11.5" sbr
Ammo: 70gr tsx
Range: 95m
Estimated impact velocity based on prior 100m chrono data for this weapon and ammo: 2350fps
