6mm /.243 hunting success on Big Game

[Axlrod]

I would debate that. The creedmoor and the 25-06 do not utilize a magnum bolt face. Just because they are “over bore” doesn’t mean they are magnums.

No dog in this fight, you can go round and round on topics like this. But a 222 Magnum holds less powder than a 22 Creed. The term magnum came from wine bottles, and I beleive thr first cartridge to use it was the 357. So it really isnt a useful adjective sometimes.

Nah you’re not missing anything. The only thing I can really think of is POSSIBLY more potential for DRT’s when intentionally shoulder shooting animals in heavily forested terrain. There’s absolutely a visible impact difference between the small and large cartridges/calibers.

Nah. You shoulder shoot them, you effect the spine which drops them with anything. Beyond that, there are bullets in 6mm that create some of the largest wounds of any caliber and any bullet ever made to this point.

I’m pretty sure these have a visible impact. grin




From another thread-


Remember this is culling. Not hunting.

If you just hit ribs, it’s good- very effective.
If you hit bone, very likely you won’t like it.

2,100’ish FPS impacts. Photos and animals are unmodified.

Quartering too- shot entered center chest… How we walked up to it. A 9-10” wound.

Facing directly away. 2,105fps impact. Entered center of rear ham- 10+ inch hole. TC blew stomach out mid belly, bullet traveled all the way through the chest and through the heart. Everything inside body cavity was wrecked.

Heart-

116gr TMK, 2,105fps impact.

116gr TMK, 2,424fps impact.

Weatherby and Lazzeroni missed the boat.
.257 Jeroboam, anyone?

Do the 116’s produce a significantly larger wound channel than the 95 at the same velocity?

Ehh. Haven’t shot them side by side. My “feeling”- is yes. They have produced larger exits than 95gr TMK’s.

Case capacity in cubic inches (minus the neck) divided by the bore diameter (in inches) squared. It's a dimensionless number which can also be derived from ml and mm.

Call it overbore, magnum-ness, or whatever.

Hi highly prefer to use the term magnum-ness, I think it's THE most appropriate here.

 

[nm.otter]

It's a useful metric, and I'd like to see it used more often.

Fair.
Thanks.

Yeah I’m definitely not saying something smaller can’t/wont affect the spine. Just that something bigger could POSSIBLY affect it more often (because not every shoulder shot affects the spine from what I’ve seen) when shooting in the shoulder. 300 RUM with a 220 TMK could potentially affect the nervous system with a shoulder shot more often than an .223 with a 77 TMK. I don’t think that’s a stretch of a statement.

I’ve seen, & have quite a few videos of the larger stuff affecting the spine/nervous system causing a DRT when placed pretty far away from the spine. Not so much the smaller stuff. And I’ve asked multiple times for .223 and 6mm kills videos to compare the actual impacts themselves, but don’t have much footage of it to share at this point.

And I agree those are great wounds. I’ve been following the thread as well. I’m sure most of those deer were DRT because of their small size vs. those wounds.

Oh gotcha. Cool ration comparison. I always just went off if it used a magnum bolt face lol. But that’s a good ratio to judge “overboreness”
