My go-to rifle for deer here in the Ozarks would be a Savage Axis in .223. Light weight, very accurate with my handloads. For squirrels, my Ruger 10-22 or my Marlin .22 bolt action.
I generally put 5 or 6 deer in the freezer every year. I don't hunt anymore. Don't have to...
So, my favorite deer harvesting tool is OTHER PEOPLES' CARS. Let me explain:
Since 1998 I have called the local cops, highway patrol, Conservation dept, or sheriff and say, "Put me on your deer list." There are a LOT of whitetail deer around here, and they often get hit inside the city limit, often around the golf course, sometimes on the interstate.
Whenever someone hits a deer, they generally call the cops & file a report. 911 dispatch then immediately calls me to come pick it up. Sometimes the cop waits for me & sometimes they actually help me lift it into my truck. One local fat guy donut eater insists that I BRING MY OWN GUN TO KILL IT! (Something something fat slob don't wanna use his issue pistol inside city limits cuz it's dangerous/loud/whatever...) Other city cop said no problem, you just call me & I'll shoot it no problem. 911 dispatch called me TEN times in 2020, eleven times in 2019. Lots of deer getting hit around here. Local butchers are covered up & won't do deer anymore, except for the short gun season, so I process them myself.
Generally, the deer has one or two broken legs and is 50% of the time still alive when I get there. I get.PISSED. because it's inhumane to let an animal lay there & suffer. I want fatass to put it down asap, but he's really fat, & won't do it. In the city, traffic speeds are slow enough that they just get bumped to the side of the road with minimal damage, but hit enough to either break their legs or kill them outright. Along the interstate, if they get hit by a truck it can smash em up pretty bad & toss it 40 feet. Pass.
Sometimes the back ham is bruised. I just cut out the bloody meat & process the rest. Fresh meat, free, just laying there very conveniently by the side of the road, dead less than 30 minutes. Bonus of a free hide with no holes, bones, sinew, brain... I've been doing this since 1998. I learned how to braintan deer skins, and will chop the head to extract the brains. Braintan deerskins are buttery soft, just like a big chamois. I'm not as good as some of my friends, but I do OK.
Backstrap sinew and leg sinew is useful for primitive arrows, tying on feathers & stone points. Why waste free meat? Eating roadkill sounds disgusting, but not the way I do it. I finally had to buy a powered meat grinder for all that hamburger and a commercial meat slicer for all the jerky I make. When cooked in chili or spaghetti, you can't tell what kind of hamburger it is... And nothing better than fresh backstrap on the grill, sliced thin! Nobody EVER turns down my deer jerky. The only problem with deer is they mostly don't have any fat on em, and fat tastes good.
On occasion, I can get a double.
Easiest one was just a few blocks away. Sometimes they're out in the county, but usually they're right in town.
I do all my own butchering. A saws-all is good. A pulley/rope system to hoist.
Only once have I ever had bad meat. Got a call one time in Springfield, Missouri to come get "two does" that got hit. Turns out it was twin button bucks running together & got plastered by the same car at the same time. One was just fine... the other absolutely STUNK! Every part of it, the meat, the bones, the skin smelt like... Really gamey. Like it had been eating onions or garlic or something. Had to soak the meat in buttermilk to get rid of the smell/taste.
(shrugs shoulders) It's just how I do it.
First deer I ever shot with a firearm, I killed with a Chinese SKS, from about 10 feet away.
