Made it out to the range today and had a nice afternoon of shooting and adjusting the rifle.
THings didn't start out too good, but after tightening the chassis bolts, scope mount/ adaptor and the rings, I final got some decent results.
I used some 150 gr. FMJBT ammo that I handloaded for my M14 initially. After about 20 rounds with a cleaning every 3 rounds, the group sizes began to settle down.
Once I was happy that the rifle could shoot sub MOA with that ammo, I switched it up to my 168 gr Hornady HPBT Match rounds loaded with 42.5 gr of Varget powder.
I shot one group at 100 yds for zero and then moved out to 300 yds. The results were alright, but I really think it's going to get better yet since I have not tuned the load for the rifle.
The Griffin Armament Tactical Compensator/ Flash Hider reduced the felt recoil down to what you might expect from a heavy .223 load.
Here are a couple pix of the 300 yard groups.
Cheerz!
