This has happened to me when I started shooting ML at them. Started with Powerbelts, went to Hornady SSTs, then landed on TC Shockwaves. Had several incidents with the first two where I had little to no blood to trail. What I figured out was most of those bullets do not have a bonded core, so if you have too much powder or maybe just the way the bullet hits, it can explode, thus no exit wound and no blood trail. In thick stuff this can lead to lost deer. The TCs worked better but I made sure I bought bonded core bullets, which are more expensive.
I ultimately switched to Barnes expanders and honestly there isn't a huge cost difference vs. the TC bonded bullets, but those things are lethal. I've only shot a couple of deer with them as I have really stopped shooting does on my main spots, and I have shot a coyote too. The 2 deer went less than 50 yds and the coyote was down right there. Blood trails were present on both the deer I shot, but I didn't need them.
