Based on my experience hunting deer with both solids, and various lead core designs, including a conventional C&C type. I didn't see any obvious or substantial reduction in meat damage on deer size quarry. They do shoot very well though, and maybe they punch through heavy bone and flesh on larger game than deer with better retention, but how much better? As I said, I couldn't see any obvious indications of less meat damage compared to a Speer Hot Core.
I can't think of one negative point regarding the TTSX, it's a very good hunting bullet. So if your anything like me and many others here, you'll probably give them a test run on your next deer hunt, just because you have that luxury as a reloader, ya buddy!
