PMme I will get you a phone number tomorrow of a topnotch guy to deal with on suppressers and a good 7Twist 30 cal barrel chambered an threaded on both ends once you decide which suppressor to use.
Silencerco Omega
I've got an Omega on 8" 300 Blackout AR. The bolt moving makes more noise than the shot with subs.
Supers sound about like a 22LR.
I did that once. Couldn't get acceptable accuracy from it and ended up rechambering the barrel to 308win and using trail boss powder. The result was better ejection, better accuracy and the same sound signature. That particular experience convinced me the aac was best presewed in an AR and it may be more trouble than it's worth in a bolt gun........just food for thought.
So are you saying it can be bought for $270.00 from Palmatto?
Mine is a 10.3" BO and it mirrors your experience.
This past summer, for fun, we had a 200 yard challenge with 300 BLK on that forum. Had to put 5 shots on a 3 x 5 index card. Oh boy was that tough. I could get 3/4 MOA at 100 yards only to have go to pieces at 200. Mind you, these were with 180 to 220 grain bullets, High ES's and SD's. Best I did was 4 on because,thank God, we counted cutting the edge. A few guys really figured it out, a lot of different powders were tried, it was a lot of fun. But by no means is a 300 BLK bolt gun inaccurate with subs. It's just hard to achieve that at distance with a bullet traveling at the speed of smell.
This was a decent entry, not mine for sure. At 100 this load was moa and at 50 about dime size. It really starts to drop off after 100 yards. To the OP, X caliber makes a good one and while I have an AAC Cyclone, the Thunderbeast is super quiet and rated for 300 WM I pretty sure.

I tried a bunch of loads. Subsonic and super sonic ran about 1.25 moa with there best loads in aac. The same barrel re-chambered to 308 win shoots just over .25 moa super sonic and .75 moa subsonic. I think it's just too easy to build in fast twist 308 with no negatives when your running a bolt rifle and since your not gaining anything by going to the aac............. In an AR it is a no brainer with no negatives. Bolt guns can also suffer ejection problems with the extra small case, not a problem with the 308............P.S. Love some palmetto stuff!!!)
