Humm....same story, different day, different person, just got this from a friend who just started MLing andbought a new Triumph and was shooting SWs in it:

Thanks for the advice on the Shock Wave lack of expansion at short range. I shot a big doe last night at about 50-60 yards broadside. It hit just behind the on side shoulder and exited through the off side shoulder.The exit hole was the same size as the entrance hole. Usually a bullet hitting the shoulder blade will open up some. This absolutely did not! She ran about 30-40 yards before piling up. But, it sure surprised me when I took a look at the carcass.

My question is why? My theory is that the bullet is too hard and the hollow point too small. Dead animal for sure, but long trailing jobs. Magic bullets are what ya need:

Magic=
1. accuracy cause without accuracy not else matter, shot placement with accuracy is everything
2. penetration is queen, accuracy is king, penetration much occur to get into the vitals of game, minimum of 12"
3. expansion to disrupt vital organs and give large wound channel, they measure wound channel by volume of water that it takes to fill the channel, a large would channel will disrupt blood flow to the brain quickly and produce boom flop or short death runs
4. shot thru, you need that for when you need to get quick recovery, I hunt on 17 acre little patches of land, and need to NOT trail a deer far, since I get the cops called on me if I go onto a horse pasture carrying a gun
5. Little or no fragementation.

Those are the characteristics you look for in a bullet. Read all you can on google about a perticular bullet, read the product reviews on Cabelas and MidWay and other supply houses. You will get a good sense of bullet, AVOID bullets that
1) pancake or expand to fast, they don't penetrate well, an example of which is begins with a P and end with a t. Look for large expanded head and LONG shank, this means no fragmentation and keeps the bullet driving FORWARD, not to the side. Shooting a PB at very high velocity produces fragmentation, you want a bullet that kills at 30 yards and 130 and 180 yards without any fragementation.
2) you want no pencil thru, you want expansion to produce large wound channel. A bullet that does not expand will NOT have the killing power for boom flop in most cases, you will have LONG tracking jobs.
3) gotta have accuracy, do NOT use a bullet where you cannot get 3" groups or smaller at 100 yards, most of the folks on here shoot 1.5" groups in their MLers at 100, most rifles will shoot 2" not problem and it will take some work to get to 1.5" groups, for hunting you don't need the 1.5, but obviously smaller tighter is better.
4) shoot thru, a bullet that does not shoot thru will kill the animal, but in most cases from tree stands it will be on off side under the skin. 250g HP pistol bullets are KNOWN to produce this effect of not shooting thru, 300g almost always shoot thru and I have shot thru the LENGTH of a deer with a Nosler partition. Shot thru is very important because you get good blood trail and the deer does not usually go far.

So there you have what your looking for to get 'magic bullets', in my personal opinion the following are
magic bullets:
Barnes MZ 300g
Nosler Partition 300g
Speer Gold Dot 300g
Barnes Origonal 300g

other bullets work for "broad side" bow shots, which honestly any bullet can do, it is getting into and thru the vitals from oblique angles and shoulder shots that makes a "tough strong bullet" the choice for me. If you study the bullets and identify the characteristics that make them kill well, you will find that I described above. Choose well and best wishes in your choice.
