What caused the Rokslide shift to smallest caliber and cartridges?

I think I'd rather have a gasser with a mag full of 77TMKs e.g., over a shotgun with slugs.

No experience but I always thought this would be a great spot for 75 Gold Dots.

 

[Bowfinn]

Honest question.

Would a larger caliber shot in same spot through the shoulders (not where a bears vitals are) have gotten to the vitals? Or caused a different outcome?

Here is a good picture of bear vitals with the shoulder. Bears need to be shot pretty far back.

Yeah. I killed my first bear this year. Shot it in the middle of the middle.

If you shoot the shoulder and don’t hit spine they just run off

That’s the problem. All we are saying is that high quality bullets in their effective velocity range will kill an animal. 223 rem or .35, put the right bullet north of the diaphragm and the animal will die quickly.

What about my buddy with 6.5 PRC that lost two whitetails in one season? Finally he got one on the ground and I asked him what it looked like when he gutted and he said it was guts soup. Turns out someone told him to shoot away from the crease to avoid meat damage. He was just gut shooting animals and couldn’t find them. The “off the crease” stuff needs to die. Straight up the front leg, middle middle elevation and you’ll get heart and lungs and it’ll die. He literally did not understand basic anatomy, perfusion, or mechanisms of death. What if he came on here and argued against 6.5’s not being enough gun? Should we listen to him? I bet a bunch of people with bias toward big guns would surely listen and quote him. Luckily I talked him out of a multi thousand dollar 300 PRC after showing him a handful of .223 kills.

Tell ya what, I’ll just use your argument back on you.

I don’t need to try a 35 bore because for 20 years of hunting deer with soft shooting, accurate 223 and 6mm guns, I haven’t had a single problem. So why would I beat my shoulder up and give my kids a fear of shooting with “big” guns?

Or I could explain, somewhat scientifically, what I have seen from personal experience. That my “small” guns cause enough tissue damage in the vital cavity to stop perfusion in the brain almost instantly. AKA, they don’t run far. It also happens they’re cheap to shoot, anccurate and gently recoil. AKA I know my limits well, and inside of my limits, I’m extremely lethal with my guns. Seems like a win win win for me.

I’d just love someone from the big bore crowd to explain, scientifically, how the extra millimeter of bullet diameter kills better. Genuine question.

You hang on to anecdotes that make you feel good and ignore everything else.

I have literally only killed deer in the last 5 years with .233 and 6ARC. Last one before those was a bad shot with a 308 and she ran 100 yards and expired, as expected. Luckily I got some lung or she would have gone much further, with probably any cartridge. Still made for a smelly gut job.

6 ARC kills are a big doe, see gaping hole above. Shot at 250
Next is wife’s doe at 200ish

Put a high quality bullet at a proper velocity right here on an ungulate and it will F**KING DIE.

Just last year I killed 5 deer, nothing but 6 arc and 223.

I am hunting elk this year, and bumped from an ARC to a 6 creed bolt gun. I’ll report back if I’m lucky enough to punch a tag. Hell I’ll report back if it works like shit, but I doubt it. I know my limits because I shoot the absolute piss out of that gun (getting used to the added recoil.) Here is my brass stack (at least what I picked up) from my training since I got the gun done in June. I feel confident that I’ll do my part and out the bullet on the money, and I feel confident that that 108 will do what it has always done, which is liquify all the goods inside the thoracic cavity.

I think we are dealing with 100 years of people shooting like shit and blaming the cartridge or chambering. Just silly and egotistical.

It really isn't going to make much difference on deer as they are easily penetrated by a lot of cartridges. I have noticed a distinct difference in blood trails, how fast feral hogs go down say when comparing my 308, 35 Whelen to a 223 or a 243 for that matter. Especially when hunting at night. You want a very good blood trail to follow when looking for a hog in the dark, you also want that hog dead. Unless one has used a 358 or 35 Whelen and seen just how effective they are on game, the short distances animals travel after solid hits you will never understand. For night hunting I put my 7-08 as a minimum if hunting thick stuff where I can't always make a CNS shot.

People are acting like 30 calibers are “big entry holes” when 223 is a “small entry hole.”

You’re talking about an entry hole that is 2.06mm bigger. Hold your index finger and thumb 2mm apart. That’s not “big”. They’re both incredibly tiny holes in comparison to the animal’s size itself.

That’s what’s comical about this all.

Funny post. I have never had to look for the entrance hole my 308 or 30-06 made but I have searched for entrance holes various 22 caliber bullets made.

O'Connor talking about fragmenting bullets on deer sized animals back in 1961 on bullets he used before WWII:

"With lighter big-game animals, the biggest problem is quick expansion instead of deep penetration. The right medicine is the bullet that expands rapidly and even disintegrates. I have gotten more instantaneous kills on Arizona whitetail deer, which dress out on the average from 90 to 110 pounds, with the Barnes pre-World War II 120-grain .270 bullet than with any other. It had a thin jacket and a soft lead core. When driven at about 3,250 at the muzzle, it was a bomb. I found that a hit anywhere near the heart would almost always rupture the heart with fragments. I never had one of those bullets pass through even a light deer or antelope with a chest shot, and I cannot remember anything but one-shot, instantaneous kills. In fact, I have even seen that bullet stay in the body of a coyote, and I cannot remember hitting a single coyote without killing it instantly."

No one is saying that a bullet weighing 120-130 grains that expands violently won't kill deer. In fact one could easily argue that the 270 is bigger than most of the Rokslide preferred cartridges which as far as I can tell are .224-.243 and burn less than 45 grains of powder on average.

This seems like relatively short range hunting you describe. If you are having trouble killing deer quickly with a 6mm there is some other issue causing that. A 6mm is more than enough for any deer at any angle at moderate ranges. If you like large caliber lever guns, that’s cool and obviously will work.

The requirement for fast shooting makes a difference, And no the vast majority of 6mm bullets launched at the speeds a 243 is capable of won't give corner to corner penetration in a 150 to 200 pound deer. A lot of shooting is offhand with maybe 20 seconds at most to make the shot. It isn't like waiting over a bait pile.

To add to this, the FBI’s own ballistics testing shows it’s not far behind a 308 in terminal performance.

The FBI was talking about effectiveness with solid chest hits in humans.

 

[FredH]

I say respectfully that you’re showing your ignorance. I shot a muley doe last year, and the 77TMK blew through both shoulder blades at distance. Tyler Freel took a moose with the 22 ARC and 88 ELD that had now problem going through the moose shoulder.

Many, many examples in the thread we’ve referred to multiple times about shoulders being penetrated without issue.

If a broadhead can go through a scapula, why can’t a bullet?

A shoulder blade is a thin piece of bone. I often wonder why it is mentioned when touting penetration.

Pretty sure they weren’t shooting humans in that test. Looked kind of like ballistics gel to me.
