Thread: 8.6 Blackout

Barrel length is important to make subs quite, longer is better

Bigger calibres work better terminally, but harder to make "silent"

Purpose built mono subsonic projectiles offer more aggressive & consistent terminal performance than cup & core

Crimping is important/imperative with subsonic loads

I crimp for 308 but the 300BLK doesn’t need it.

Whats suppressor’s are everyone using?

I am using a purpose built eccentric over barrel suppressor on 3” dia tube
450 long is super quiet first one was 300 long but didn’t have enough baffles in front
To work the best with subs vs bore diameter

Other option would be somehting you can add to and chuck a few extra baffles into
If going the dedicated sub route

Definitely haven't needed to crimp any of my rounds. There's heaps of neck tension what with it being 338 bullets shoved right into the neck - they ain't budging. Powder's burning well and getting great ES/SD's.

I'm using an A-Tec MH2 on mine. @NCGNSMITH, I think I was the customer that passed through your place. Blue chassis?

Dpt :-) dare I say

By the way, it was the peregrine projectiles I was waiting for not maker.

Any chance of some photo's and a bit more detail on your suppressor? I was talking to Ian from Hardy's a while back who runs an 8.6 blk - he made a custom suppressor for his.

Hi
I can give rough specs but not at point I want to post pictures

450mm long
3” dia
480 grams
250mm muzzle forward in current configuration 8 baffles 2
Swirl baffles
QD muzzle brake system to remove in couple seconds
At the moment the rear bush is a second mounting system/lock stays on
Barrel when suppressor removed
When fitted suppressor sits 25mm above barrel centreline with a 20mm
Internal Isolator tube
The downside is the current cost
12 plus hours and a serious chunk of alloy with a handful of titanium go into
them
It was more of a wonder if I can make it project
