Best bullet for subsonic 308

Re: Best bullet for subsonic 308

I use 180 gr round nose with 10.0 of trail boss and hornady brass just start higher without the supressor on when testing about 1050 to 1080 is a good range for subs.

The 12tw may or may not stabilize for the OP, definitely worth a try.

If it doesn't, then here's a load that works great for a friend with a 12tw, I'd suggest starting 1.0gr higher and working DOWN in 0.2gr increments

9.5gr Trailboss
150gr Winchester Spire Point
OAL @ 2.700" OAL
