This thread has been downright comical to read. Can certainly differentiate the guys who are shooters versus the guys who peruse Chuck Hawkes website for their "knowledge".
The fact that some folks are fixated on headstamps and websites and barrel length and "energy" (how many energies does it take to kill something?) instead of bullet selection says volumes as well.
To the OP, you never indicated your province of residence as near as I could see, but as alluded to in a few posts, there are caliber restrictions in a couple of provinces. BC is not one of them.
You'd be hard pressed to go wrong with any of the 22 centerfires for your intended purpose, if you choose the appropriate rifle (twist rate is very important) and bullet combination.
.223, .243, 22-250, all will work for your intended purposes. Just try to pick the right bullet for the job. And pick the right twist rate for your intended bullet choices.
As an aside, my do-it-all rifle this year is chambered in .223 Remington. 62gr Federal Fusion SP's are it's chosen fodder. I'll try 73gr ELD-M's if I can get my hands on them though. Coyote's to Moose and everything in between. Lots of people would think I'm mad. And I can't blame them. Conventional wisdom says it's incapable of killing even moderate sized ungulates, let alone big ones. But a body of evidence has been presented to me that makes me believe that to be untrue. We'll see though. I have yet to kill anything with it. If I pull the trigger on an animal, I'll post my results, good or bad for all to see.
Dorian, the Fusion is a pretty reasonable bullet. The 73 ELD m's are a whole other level of lethal though, if you have the twist rate to spin them fast enough to really squeeze the good stuff out.
My everything rifle this year is a 223AI 1:7 twist. It's been to Stone sheep country among the grizzlies so far, to Haida Gwaii for a few days, and the back 40 for elk. This weekend it is on black bear duty, and in a few weeks it'll go hunt moose on our 2 day season as well. And it'll smash a couple big northern bucks to the ground as well at some point in November.
The bull elk that crashed to the ground a couple of weeks ago fell over just as decisively as anything else that I've stuck an 88 ELD-m into, and faster than any of the elk that I shot with a TSX or TTSX from larger, much larger, and way larger cartridges.
Bullets matter more than headstamps. Bullets are the only interaction we have with the animal if we choose the right ones..
