I am running the 85gr TSX in 243 as well, I also have not killed a deer with it. Shot a coyote on the run at ~ 30 yards... exit was nasty.
I shot a coatimundi with it too at ~ 150 yards but I think I skipped it into the thing. The entrance wound was in the belly and was... large. The bullet was in there too and was smeared and only about 60% had been retained. I didn't really count that since I'm pretty sure it skipped in. His pelt is due back within the next month
I think I lost that bullet so no pics.
