8.6 Blackout vs 375 Raptor

Who has shot both? Your thoughts? One has two inherent flaws: fast twist rate, and chambers in a .308. The other one does not.

I think the Raptor is more impressive ballistically, and the cooler round for sure. Obviously 8.6 is seeing a lot more commercial success due to a huge marketing effort behind it, better suppressor selection and availability, and more factory ammo options.
But if you’re committed to the idea of subsonic hunting, I think the 375 Raptor is the clear choice.

I second this.
I load 270gr supers and 400gr subs for my AR10. It's a super versatile cartridge with a more efficient burn because of the larger bore diameter. A good suppressor and an adjustable gas block are a must to discover what this round can do... which is a lot!

Honest question. Who cares? Both are gucci ass rounds that cost nearly as much as a box of .223 pre covid. I have a feeling anything that's killed by 8.6 also dies by .308. Yes, I have a suppressor, no I don't care.

Someone is a bit angry that they designed a new round without telling him first. Get over it. You probably only own a 308, 556, and 22 because “Ammo’s cheap”. There is something called branching out to new rounds.

Some of us like wildcats, tinkering is part of the fun. If you dont like them, thats fine, just move along.

I love 300 blackout. However
As a subsonic thumper, 8.6blackout is a meme round. that might be the first time I’ve made that accusation of any cartridge
-288gr is hardly an upgrade from the 220gr 300Blackout. When you need to stay subsonic, velocity is capped at ~1100fps so increasing mass is the only way to increase energy
ALL OF THIS CARTRIDGE DEVELOPMENT FOR A MERE 30% INCREASE IN MUZZLE ENERGY OVER 300 BO
-STILL hasn’t been developed well enough to be actually accurate. And it’s iNsAnE sPiN requires weird adjustments inside of 500yds? ….. Meanwhile it’s ruining user’s suppressors
-marketed as able to take dangerous game: the subsonic 228gr has the 770ftlb- roughly same muzzle energy as a 44magnum.
-costs more than 375 or even 458 socom, which has subsonic loads up to 600gr- over double the muzzle energy of 8.6. 375 comes in at 400gr. Still pretty awesome.

a couple minor corrections: maker is producing a 350gr bullet specifically for the 8.6. that IS a substantial improvement over 220gr 300 blk, but still not as good as 400gr 375, or anywhere close to the various 458 caliber heavies. secondly, 44 mag can pretty easily break 1200 ft-lbs in a 7.5" barrel, and is WAY more powerful than subsonic 8.6 lol.
100% agree that 8.6 is a wildly overhyped meme round.
Dude_I_got_a_DWAVE@reddit
Yeah- 770ft-lb is pretty much basic range 44mag- nothing special.
350gr starts to make more sense for 8.6
PrairieBiologist@reddit
The difference being that because of the difference in BC the 44 magnum loses a third of its energy at 100 yards whereas 8.6 only loses 22% of its energy through 500 yards.
TravelLopsided6980@reddit
what we need a is a heavy cheap, good bc round. like a 458 socom that was more efficient, accurate, and common
PrairieBiologist@reddit
I think you’re totally glazing over the difference in ballistic coefficients. 8.6 blackout with a 300 grain projectile has a BC of .750 compared to whereas a 500 grain .458 socom only has a BC of .44. The 8.6 is retaining 78% of its energy through 500 yards. With 342 grain projectiles it’s maintaining 80% of its energy at 500 yards.

While 250yards is the commonly given maximum range for 458, Kevin himself says 8.6 is good out to 300yds Subsonic
At 300 yds, 8.6BO subs have dropped to 600ft-lbs of energy, while a 500gr 458 is still pumping out 885ft-lb. At 300yds, 8.6 has 68% of the energy that 458 does.

Is the fast twist rate not kind of it's selling point?
NEp8ntballer@reddit
That's what KB is saying. I'm not sure if I buy the idea of rotational energy, but it does impressive things.
Gews@reddit
The guy doesn't know what he's talking about. This is nonsensical babble:
"Fast twist barrels provide much greater energy with supersonic"
"... a 1-3 twist, so we’ve settled on the twist. We’re using some of the energy that is wasted, converting that to kinetic energy now by spinning the bullet faster. So in supersonic, it is more kinetic energy on target by spinning the bullet fast."
You can't increase the kinetic energy by changing the twist rate from reasonable, to 1-in-3". If anything, such a fast twist could reduce the overall muzzle energy.
It can affect the bullet performance, though. Just look at how some bullets explode into lead mist if you spin them too fast. I still think it's dumb.
CoreMillenial@reddit
Yeah, I don't claim to really get it, but I suppose the proof is on the pudding.
And by pudding, I mean his pile of dead exotic animals.
gasfng444@reddit
Are those Maker bullets?

375 Raptor FTW
Such a satisfying thumper.
