For several decades now, I have not been interested in hunting with self-loading / semi-automatic rifles and shotguns.
(Weapon designs for self defense are in their own category, separate from hunting, IMO).
Anyway and instead, I definitely favor manually operated rifles and shotguns for hunting.
That is partially due to my leaning toward fair play as I age, (more now than ever).
And, it’s partially due to my ever increasing dislike for disassembling cleaning and reassembling complicated mechanisms —> AKA: “Lazy”.
However approximately 40 years ago, I successfully hunted caribou with an M1 Garand.
Mine was made by the International Harvestor Company, I suspect sometime in the 1950’s ?
The bore was festooned with countless tiny pits, showing a “dark appearance” the full length of it.
But nonetheless, it provided somewhat acceptable accuracy, sort of.
This, considering the bore looked like the inside of a .30 caliber diesel exhaust pipe.
As far as factory loaded ammo went, my particular M1 favored Remington 150 grain “Core-Lokt” spitzers.
Caribou look larger than they really are, perhaps because they usually (usually) inhabit treeless landscapes.
Also, they are not especially “impact resistant”.
Mule deer are much tougher, in my limited experiences.
And so, the .30-06 is more powerful than necessary for caribou.
But it is comforting to carry the 8 shot M1 where grizzlies are common.
I kept a couple of standard 8 round clips on my person, loaded with the same ammunition mentioned above for my hunting purposes.
In addition, even though I have never been forced to shoot an aggressive bear, I did also carry an 8 round clip, loaded with heavy bullets in it, always ready in a dedicated pocket.
For those who enjoy semi-automatics for hunting, I have no quarrel.
But for myself personally, I have lost interest in such contraptions and am happy hunting with earlier conceived, more traditional designs.
