Super interesting results. the TTSX usually stay together at way higher speeds. Can’t imagine that’s different for this one. The lowest speed cartridge Barnes has load data for on the 160 is the 338 Federal at 250 ft/s more out of a 24”. So I assume it is the rotational forces vs. the gel the bullet can’t keep up with. Would be interesting to check that with a shorter barrel 338 Federal at similar speeds
@@newscoulomb3705 yep, which is somewhat surprising as the actual energy stored in the rotation is surprisingly low. But then the cross section is not designed the peel to the side.
One of the sturdiest copper bullet designs turning into a frag grenade at pretty low speeds … Makes me wonder if a dedicated copper bullet design is optimal for the 8.6. I would go with diagonal peel back fault lines in the direction of the twist. Should in theory reduce the forces on the petal cross section. In the end what’s cool about the 8.6, the high speed blender 😁. No petals no blender
Is this the 1:3 twist rate ? I’m trying to do the same thing on a Lee Enfield, 303 based cartridge 1.8 twist . Goal is a dual purpose, pig buster ! With play time & experiments with the heavier jacketed & cast stuff.
@@concernedaussie1330 it is the 3R twist. I tried some jacketed bullets but the 16” barrel didn’t treat them very well. Lol. They pretty much disintegrated right out of the barrel. 🙄😉
@kentuckyrangetime thanks mate. My local only has 10 , 9 or 8 twist barrels. So I'm going 1:8 . Thinking my 19" 303 based 338 will sit somewhere in between the 8.6 & the 338 fed when using full power loads . Hopefully, this will be a great cast lead rifle.
@@jasonshults368 there’s definitely a few things that can really help cast lead operating at these quite extreme twist rates. Even 1:8 is considered to fast by many ! However, the results that 1:3 twists induces on monolithic’s & destruction it causes to jacketed, hopefully will have a more balanced approach on lead @ 1:8 & conventional jacketed. And being far more cost effective for the average joe . My goal is to shorten the 303 case , but still retaining maximum case volume & limited case trimming. Basically making the most out of the limited constraints of the lee Enfield action & 303 case. Cheers.
@@phild9813 Not sure I could hit the gel at 300!!! 😂😂😉👍🏻👊🏻. IF I had more time and more $$$, I thought of taking velocity data at further distances and load down a few loads to that velocity at 15’ just to see. But that’s a project for retirement in a few years. 😂👍🏻
@@kentuckyrangetime awsome i have a q fix and i tried 34 and 35 grains. Had minimal pressure signs and the 35 was a touch more accurate but i hadnt chrono’d it yet. So was glad to see someone doing the same thing
@@liverpool6380 Hadn’t thought about it like that but maybe. 😂. I guess the exception is I have the option of running 350gr loads suppressed out of the same platform. No way my .308 AR-10 is going to manage that as effectively. The built the 8.6 for the suppressed capability, shooting supers is a bonus. 😉
Wooohoooo! 8.6 blk! Loving mine! Looking forward to testing it out on some deer (Lord willing) this season with some Makers running subs. You gonna do some more subsonic tests too? Please !
That would ruin a feral hog’s night. What was the powder load you used just out of curiosity?
You can find load data for this specific bullet and powder on Faxon’s website. They show 2,400 fps out of a 16” barrel.

The twist rate for 8.6 Blackout is three times faster than 338 Federal, so these bullets are almost certainly spinning fast enough to disintegrate.

That would be a great cartridge in a 8 inch barreled suppressed mini bolt action

@@nikos6220 absolutely!! 😂😂.
The 342 Gorilla and 350 Maker subs both have done Spiraling showing on their petals. It pretty impressive. Lol
@@kentuckyrangetime the spiral on the 342s is just crazy
That twist rate is too much for a super. It'll probably disintegrate more often than not.
@@peady64 With jacketed lead bullets you’d be correct. That’s why all these supersonic loads are all copper bullets. 😉
I load those in 338lapua at about 3700fps and they're insane
@@livingintheLight. I’d say!!! 😂😂
What's the barrel length?

Interesting! I appreciate experimenters. If you can use powder-coated bullets, they will withstand the 1:8 twist rate better than naked lead.

Have the same loading im using 35 grains what grain of powder are u using?
@@tylerstiltner2397 I’m at 34gr of AA-1680. It’s just below pressure signs in my rifle.

Did you just turn your 8.6 into a larger diameter 308
