Are you implying that it isn’t possible to hit a deer well when using a .224 caliber rifle?

I’ve never shot a deer with anything bigger than a 458 Win or smaller than a 222. And I’ve never shot anything bigger than an elk with a 22 centerfire. Probably not talking anything much over 400-500 head of animals killed discounting varmints like coyotes and Pdogs. If you hit them right it doesn’t make much difference what you’re hitting them with in my experience, hitting them right is the important thing. And when a good bullet from a 223 will give over 2 feet of penetration and leave a 2” wide wound channel the margin for error argument doesn’t hold much water with me.
