Is there a subsonic .308 round?
Yes their are, but I roll my own.
.308 subs are not cheap
I loaded some 170gr subs using 30/30 bullets (this is back before there even was a 240gr SMK) and somewhere around 9.0 grains of Trailboss.
I set up a backstop in my basement comprised of 1/2 gallon water bottles inside empty 30 gallon HDPE drums, back up by some 1x4 wood planks just in case. After firing the round I found that it penetrated all 7 bottles of water, both sides of both drums, but didn't penetrate the first board, just keyholed into it. I went up stairs and said "Did ya'll hear something?!" The ol' lady said "Uh, nope?" I said "Huh." went back down and clean up my mess.
This was with a Remington M40A1 clone with an SWR prototype suppressor.
It would not function in a semi, but I used the load in my AR10T and it worked like a straight pull bolt action. After firing, the bolt carrier would unlock, and retract a bit, but not enough to cycle a round.

Delicious, simply delicious. That's all that can be said. Question, once you get a SBR license do you have to get one for each gun or does the one license cover all the guns?
Nope, no license, but a $200 tax stamp for every NFA item. ($5 stamp for an SOT/07 FFL made AOW.)
That's good. I need to apply before I put my upper and lower together and start on my SBR AR15 5.56. I have the 6.8 done I just have to either pin and weld the muzzle brake or apply for the stamp. I have parts taken out of it so I don't get nailed for having one close to being ready.
Sig SBRs shoot so smooth but suppress so badly.. blows gas in my face so bad. I have to get the piston bored out a little bit.
