Changed out a 18 Faxon Gunners profile barrel, (didn't play well with Specwark suppressor ,5 inch groups at 100 yards) to a Ranier 18 inch rifle gas length Fluted Ultra Match 1 in 7.5 twist .
All shot suppressed off bench
Random ammo selection worst groups to best
Granted I'm still working on the 100 yard zero but trying to find factory ammo that it likes, then maybe try loading some 77 smk for it
