Anybody using them if so what powder and does it cycle what barrel lenght are you using
Ive got 10 noveske barrel suppressor pending
I'm using converted brass with 10.4 grains of 1680 seated to mag length. Out of a 10.3" barrel with a can, I'm getting an average velocity of about 960fps. They cycle fine and lock the bolt back on an empty mag. The velocity was the average over 20 rounds, and the SD was in the teens.

I use 10.4gr of 1680 for the powder. The C.O.A.L. is 2.180 and I am shooting out of a 8 inch Noveske with an AAC 7.62SDN6. I am getting a little more velocity than the above poster as mine average a little over 1020FPS. The standard deviation "SD"was good with the 10.4 as it was around 30 FPS with two dropping down to 960FPS and one going to around 1070FPS. Most fell well within 1000FPS to 1040FPS.
It cycled flawlessly for the 200+ Hornady 225gr BTHP match that I have shot with it. The Noveske had no problems ejecting, picking up the next round or holding the bolt back on the last round even when filthy. It must have the suppressor on to do it though. Without the suppressor it would eject the case and usually not pick up the next one. It never held the magazine back without the suppressor either.

I have run the 220gr Match Kings and had the same results. Noveske optimized their barrels for running subs with a silencer so as not to over gas them with the supers.
I have no problem with having to have my silencer on when shooting subs to get it to cycle because without the silencer on the rifle the subsonic ammo is about as loud as a non suppressed .22. I find there is very little use in running subs without a suppressor.
If that is a deal breaker for you AAC uppers are made to cycle subsonics without a suppressor along with a number of other manufactures
