Well not a big thread and varying opinions. Killed just two deer with them myself. Not impressed though they shot well.Hornady Frontier 75 grain HPBT is my go to ammo for Thermal pig hunting when I’m running a 5.56/.223. I’ve had great luck out of it in 16” and 11.5” rifles. I’ve killed well over 200 pigs with that round along with a handful of coyotes and bobcats. I wouldn’t hesitate to shoot a deer with it. I’ve also ran quite a few 68 BTHPs when I can’t find 75s and they work well also, but I definitely prefer the 75s.
I’ve also ran handloads with 105 BTHPs in my 18” 6 Creed and killed a dozen or so pigs and coyotes along with two or three deer. They don’t seem to perform quite as well as 108 ELD-Ms...
