Do you consider Hornady Ballistic tip ammo as crappy? FMJ/TMJ ammo will penetrate car parts. Do you plan to hunt with FMJ/TMJ ammo? I am not the only one that has seen quality bullets fragment when striking brush. Varmint hunters have all seen quality bullets disintegrate when striking a blade of grass.
In a lot of states the .223 isn't considered as adequate for deer hunting. I have seen deer run for close to a mile after several hits in the breadbasket with a 223.
I belong to a club that drives deer with dogs. We have 35 dog owning members. Every year we have guests that show up with an AR 15. They shoot deer and hit them but the deer keeps running for another hunter to put the deer down with an adequate rifle or a shotgun slug. They cry that was my deer but the rule is if the deer is standing the last person to shoot it claims the deer.
It is unethical to hunt with a rifle that will not put a deer down without perfect shot placement. No hunter is a perfect shot. We all make mistakes and sometimes we take shots we regret. If the cartridge you are shooting doesn't create enough hydrostatic shock to knock the deer down for a quick follow up shot, no matter where you hit the deer, it is inadequate.
I have gut shot deer with a 30/06 that didn't run 50 yards. I hope all your shots are true. But if you hunt long enough your bullet will ricochet off a limb or you will just take a poor shot. No one is perfect. An adequate rifle is helps imperfect hunters make clean kills when everything doesn't work out just right.
