^^^ So your first choice for hunting elk would be a 223?
Last year the 223AI and 223 were the only chamberings I carried. The 77 TMK and 88 ELD m were the only bullets I used.
Elk and moose are the bulk of the red meat consumed in my house. Suffice to say that they are an important part of my grocery bill every year.
We get a pair of two day moose “seasons” here now - spike/fork, or tripalm, or ten points only. Not the easiest thing to come by, with 40 total hours of huntable time. 3 years in a row I fielded a 223AI with 88 ELD m’s. 3 bulls in a row. 3 years in a row with major bones and supporting structures broken and bulls immediately down and dead.
This year, for elk, I’ll carry a 22 Creedmoor Montana that is almost done being built.
But I’ll carry the 223AI for moose again.
To be clear, I think people should use whatever they are most comfortable with, that brings them some personal satisfaction.
I’m not telling anyone they should run out and buy a new rifle to hunt with in any chambering, for any reason. Use whatever works for you.
In a traditional “big game cartridge” it’s harder to get bullet choice wrong buying ammo off the shelf. Most anything will work from a 30.06 most of the time. But you pay a price in increased cost/noise/muzzle blast/recoil. And very few people know what their impact velocity will be once it’s past the muzzle, and even fewer know what to actually expect from the bullet they have chosen. Impact velocity is the important variable, because it drives bullet expansion characteristics.
It’s pretty easy to pick out the guys in threads like these who fall into that category, as they typically are talking ethics or morals and fixate on chambering, but don’t mention any particular bullet, other than possibly a weight. If a guy isn’t talking specific bullets and showing an understanding of minimum requirements for impact velocity for that bullet, then he is out of his depth when it comes to talking about terminal effects of the smaller cartridges.
The one thing that has been abundantly clear on multiple forums though, is the guys who are loudest and most against it, are typically guys who are most closed off to the idea and won’t think about it rationally.
I used to be one of those guys. 20-ish years ago I remember going off on Bartell for shooting a mulie buck with a 40 gr BT (I think) from a 22-250 (I think) on the old Predator Masters forum. He likely doesn’t even remember that, as my rant would’ve been lost in the noise of all the other rants.
Long way of saying, if you make good choices around twist rates and bullet choices and operate within appropriate velocity parameters, you don’t give up much of anything in performance.
