It's not like you would think. I put an 85gr Hammer Hunter in a buck with a muzzle velocity of a touch over 3400. We deboned that deer in the field the next morning. The far side shoulder had a bullet diameter hole through it with no bloodshoot....it was quite literally a 'eat up to the hole' situation. I was really surprised. The 4 deer I shot with the 25-06, while the organs were liquified, the meat damage was less than I'd expect from a traditional cup and core bullet.
There are a lot of similar comments over on HammerTime forum on the lack of bloodshot meat from Hammers. However, it does seem like their new tipped Hammers, the HHTs, are resulting in more terminal trauma and result in more meat loss. I've got a load developed for my 270 WSM using the 122gr HHT that's shooting 0.4" groups at 3373 fps. The lower velocity should help keep terminal damage down.
