I was Caribou hunting in interior Alaska two weekends ago and was fortunate enough to shoot a decent bull, and fortunate that he left a good blood trail to enable recovery. The animal was about 350 yds away and was shot with one of 'elkaholic
's 190 grain SXR bullets from a .300 Win Mag. Muzzle velocity is about 3075 fps. Bullet entered and exited the ribcage on a mostly broadside shot.
Here's a photo of the blood trail I followed to track down this bull:
Massive blood loss out both sides of the rib cage.
And a couple photos of the bull caribou:
This bull traveled about 40 yards after bullet impact, and as you can imagine, the trailing/tracking job was not too difficult. Very nice to have caribou meat in the freezer heading into a long Alaskan winter.
