Ummm, I'll pass on the liver shot, I've tracked too many that went 200-300yds with only a drop of blood every 20' or so, not fun in brush, one took 3 of us well over 2 hours on our hands and knees, they just don't bleed enough outside. That one was shot with a .308 Winchester by my huntin partner, the deer was standing behind a tree and he thought he had a clear shot just behind the shoulder, but he hit it just a little too far back, so it just depends where it gets hit in the liver. The big buck I killed with my BLR was hit thru the liver and out the left front shoulder, it went about 30yds and piled up, so liver shots can be quick, or slow, but not a sure quick kill and they don't leave much of a trail, he left no blood on the ground, it was all inside him.
