In the last few years I’ve shot or seen deer shot with a 223 (4 deer), 22-250 (2), 244 (1), 6.5 (3), 270 (2), 308 (1), and 30-06 (4) plus a few with arrows. All aiming for the boiler room except one neck shot with the 244 Rem. All of them ran an average of <50 yards and piled up when hit double lung/heart. Only had one do a bang flop. If I didn’t know the cartridge used I couldn’t tell you what was shot with what excluding the broadheads. The only rodeos were the neck shot, and one with an ‘06 that we did not recover before yotes destroyed the impact evidence. The neck shot was super confusing but that doe is alive today a year later verified by trail cam. All were with bonded, monos, or cup/core hunting bullets. All this to say I have no issues shooting deer with 223 fusions/gold dots. (Yet to try the 77tmk.) And that I don’t prefer monos except in the 22-250.
