My pet peeve is the goofy "We owe it to the game animal to use a caliber that will provide humane kills" arguement.
It may be your pet peeve, but it is certainly something I hold to be true. While I believe I could easily kill elk with my .22-250 I wouldnt try even if it was legal. I have a .257 Roberts pushing 115g TSXs to 3000fps and 120g Grand Slams and Partitions to 2900fps and am hesitant to use it on elk. I want my game to die as quickly as possible with as little suffering as possible.
What an oxymoron there is absoutely NOTHING humane about sneaking up on an unsuspectin critter shooting it chasing it down gutting cooking and eating it. And yes I'm a hunter.
The humanity comes from respecting the game animal and killing it as quickly and cleanly as possible. For me that means choosing a suitable cartridge and placing it with the utmost care. Yes, the animal still dies.
I can't help but wonder how this arguement would be looked apoun by our foerfathers 125 yrs ago when they were killing for meat with things like 44-40.
I suspect many of them would have agreed and used something better if it was available.
The bottom line is that ANYTHING that shoots in the hands of a hunter will kill medium sized game. This does not hold true for a "rackhunter"
A meathunter armed with a 22lr rifle is gonna be more effictive than a Trophyhunter taking a 500yd potshot with a 300win mag because they can't pass up the opurtuinaty to shoot at an animal.
Maybe, maybe not there are way too many variables not considered. I have seen quite a few shooters that would have no problem taking a 500 yard shot and making it count. And yes, some of these are long past the need to hunt meat and are what you would consider rackhunters.
Over the years I have passed on far more shots at elk than I have taken, but every shot taken has resulted in meat on the table. I would much prefer the .300 Win Mag over a .22LR. Two years ago I used a .45-70 with great success but did so with the full knowledge of the limitations imposed by my choice. Placement counts for an awful lot, but it is not everything.
The flip side of your argument is that we dont need to consider the suffering a game animal might endure on its way to our table. Frankly, I find that argument repulsive.
