8.6 blackout, opinions?

[ISS]

Why not make components purchasing easy on yourself and just do a 338/ 7.62x39?

I was chasing my tail with the "published" data that Q provides. The info for the 300 SMK bullet was way under what it needed to be. I stole some information from another forum, and this all jives with reality. Had a great day shooting it today.


Sierra SMK 300 gr.

Powder: Accurate 1680 16.5 gr 1088 FPS

Powder: TAC 18.0 gr 1084 FPS

Powder: CFE BLK 17.0 gr 1088 FPS

OAL: 2.670”

If you REALLY want it super quiet, try about 6 or 7 grains of Unique powder and work around there. You’ll be amazed at the difference what lower muzzle pressure in the can will do

The components are easy... They're all off the shelf... including the reamer.

I think it's more appropriate to call it a 338GT - 6GT cases necked up are a perfect fit.

Now that I know it works... I'm going to invest in a 338 suppressor. My local gunshop has one, and a silencerco kiosk... should be easy to get.

Get something that will work up to 36 cal to cover all the fun stuff!! 9mm subs suppressed is the MOST fun!!

Omega 36M. It's full auto rated.

I built a Form 4 can... it works really well, but i don't want to bore it out to 338.

That’s the one!! Will work for everything!,

I'm excited to get it. Wait times are negligible right now. I don't NEED it for anything I do but damn it's cool.

Naturally the 8.6 blackout looks like fun too, especially with this 1 in 3 twist. I can only imagine the fun that would be shooting suppressed. The fast spin may be a marketing gimmick or maybe it’s really something new and different that works.

The 1 in 3 Twist is required to stabilize the heavier bullets.
