So..., you popped a deer with something like a 200 - 250 grain projectile and a screaming hot load. Yet the bullet didn't pass through, and poor blood trail. The ancient .45-70 cartridge would pollaxe deer out to 200 yards (and bison at 100), with a 405 grain lead bullet and a mere 70 grains of black powder, so there is something wrong with your bullet, and that hot load may be contributing to the problem.
Well the boys who made the suggestions above, like me that shoot traditional round ball, drop deer within sight of where we hit them and yes we do reach out beyond 100 yards. Elk too, and some of the fellers go for Moose with success. On deer we get pass through, and both lungs deflated, or a shoulder shot that smacks the spine too. Yet I don't get the impression that you're willing to switch to a traditional ML.
Moving on.....
IF you're dead set on that 120 grain powder load
you probably should dump the TC Shockwaves, and try the TC Mag Express
https://www.midwayusa.com/product/1...-with-240-grain-hornady-xtp-bullet-pack-of-30. Patocazador is right, those bullets are Honady HP XTP's and will probably not too well at lower velocities.
On the other hand, if you might want to give your shoulder a rest, I'd suggest you back off to about 80 to 95 grains of either black powder or a granular substitute, and shoot these all lead bullets in a sabot
https://www.midwayusa.com/product/2...240-grain-lead-hollow-point-bullet-pack-of-20 Don't let the name fool you,
if they didn't work they would have been discontinued for lack of sales. See I think what your shockwaves are doing is what the original pointy minnie ball did back in the 1860's when they were tried on large game..., i think they are deflecting on impact, or since they are jacketed, they may even be separating and the core deflecting, and then breaking up. (The original conical, rifle bullets were reviled for hunting big game, especially large dangerous game) Now the XTP's are pretty flat nosed, though jacketed so with that whopper powder load might do very well, and the TC Cheap Shots are all lead hollow points and with a moderate load, will probably surprise the heck out of you.
Of course the folks that sell sabot bullets are in
business, so if you want to drop that extra $5 -$10 per pack of jacketed, spitzer pointed, sabot bullets, and take your chances, disregard what I've written.
