here's the chronograph data so far:
125gr Nosler BTs

LC formed cases with CCI SR primer
OAL- 2.085"

SD 18.6
group size -(50 yds) 2"
220gr Sierra OTM
10.5gr IMR 4198
same case/primer
OAL- same

AD 11.4fps
Energy/range (10ft off muzzle) 621ft#s
SD 14
without the suppressor none of the subsonics cycled the rifle. They would extract, eject (sometimes stovepipe on lower powder charges of H110).
It needs the supressor to have the backpressure to cycle. Also, barrel and gas system are a 16"bbl and carbine gas system. Carbine buffer/spring.
Hope this info is helpful. If I could post pictures I would post targets too.
Also, the rifle has a 16" carbine barrel and gas system and carbine buffer/spring. Hopefully I'll be testing the subsonics through the can next week if I can convince my dealer to bring it out..........
