Hello,
My first suppressor is a Sig Sauer SRD762. I purchased it for my bolt action 308. Reading the Sig manual it is telling me I can only use a max 7.62 1/10 twist and 175gr bullet. The only .308 Win 175gr subsonic ammo I am finding requires a 1/12 twist to stabilize. I have a 1/10 twist which seems to be a 308 standard. Did I get the wrong suppressor in that it is severely limiting my ability to shoot subsonic with a .308 or just not understanding what I am reading? Do I need to get a new barrel for my rifle with a 1/12 twist rate? Will it FUBAR my suppressor if I use 180 gr or 208gr ammo? Thanks in advance.

Ive shot up to 240 grain through mine with a 1:10 twist. See thats what I get for not reading manuals.

To put things into perspective:
Helpful info from net you might find useful:
"Most modern AR-15 barrels will come in three twist rates: 1:9, 1:8, and 1:7.
The 1:9 barrel is best for stabilizing lighter and mid-weight bullets between 45 and 77 grains.
The 1:8 twist barrel is the most versatile of the bunch, the perfect option for16-inch carbine AR-15
(the most common configuration on the market."
Example: Smith and Wesson 41 5.5" barrel has a 1:16" (?) twist.
The Ray-Vin Bully Barrel is a great 1:8".
The Aquila 65gr 'fatties' are stabilized easily in this barrel.
Not to be shot out of original S&W 5.5 barrel.
Thus I infer that 1:10" twist is better than 1:12" than 1:16" twist.
My simple minded conclusion is that you are golden.
It will be fun to see if I am incorrect and full of 'Ocasio'.

Howdy!
I’ve got the SRD762 direct thread too. I use it on my 308Win RPR (20” 1:10) and 300BLK (8.5” 1:8) AR pistol. Been impressed so far for the money!
I’ve shot a variety of 308Win loads thru, including precision 168gr TMKs and even homemade subsonic loads where I simply put a 300BLK recipe (11.4gr A1680 under 220gr polymer coated lead or 208gr BTHP). Hilariously quiet, but shoots 6 feet lower than regular 308Win at 200 yards (obviously). Turned some heads at the range - always good to start a silencer discussion with folks who still think they’re illegal or “take $1,000 license to get one.”
You’ll be fine. Probably. Ha! Just go enjoy the can. Lawyers write the manuals and are extra crazy cautious.
