How many deer have you .223 users wounded and lost?
So, interesting thing… I started my kids (still all they use actually) out with a Ruger compact 223, as well as my ex’s daughter.
The first year we had a pretty good set up for kids, solid rest, exactly 101 yards. The kids took 3 whitetails there, and my ex shot her first whitetail there.
Same presentation (EXACTLY the same) quartering in, 101 yards. 3 kids, 55gr gmx, smash front shoulder onside, rake back through heart and lungs. We had 2 exits just behind the last rib, and one caught under the hide just behind the last rib, lung soup and hearts with all the plumbing torn off the top. 2 out of 3 went straight down, one half flopped 12 yards.
Ex had the exact same presentation, except a 7/08 and 139 sst. Pretty solid deer medicine in ANY regard. Deer made in 50 yards, smashed onside shoulder, lung soup, no arteries, bullet hung up in the diaphragm. About 10” less penetration, internal damage indistinguishable from the other 3.
I’ve seen a LOT of deer and black bears killed with a 223/223AI over the last 15 years and at some point enough penetration and internal damage has to be enough to be recognized as perfectly adequate to kill an animal.
Picking the right bullet matters far more than what headstamp is stamped on the case that drives it.
I also realize a lot of guys also don’t understand that, and choose horsepower and displacement thinking it will overcome poor shot placement or make up for a lack of knowledge of what to expect when a bullet meets a body… So if it makes you happy shooting whitetails with a 300wm and some Winchester white box 180’s then you do you, but it won’t make a deer any more dead than a 223 with a 62 TTSX.
