Barreled action in 223 Remington with full-bore chamber. It has a Stiller Predator 223 Remington action and a 30 inch Brux 0.218”/0.224” Bore/Groove, 4 groove, heavy Palma barrel with 1:7 twist and 11-degree target crown with 0.200” parallel side PTG recoil lug. It has a pinned 20 MOA scope base. 703 rounds have been fired through the action.

DETAILS
I had this barreled action built by David McGrath at Precision Shooting Services in Daytona Beach. He used a new Manson 223 Rem Fullbore T.15 finish reamer that provides 0.155” freebore. Best accuracy was initially achieved with Norma High Performance 223 Remington cases loaded with 90gr Berger VLD bullets at 2.70 COAL (0.010” jump to lands), 23.2gr AR-Comp, cci450 primers. 2759 FPS muzzle velocity.

Accuracy performance with HS-Precision Stock and Jewell Trigger off Harris bipod.
200 yards: 0.24 MOA based on average of three, 3-shot groups measured on paper
600 yards: 0.49 MOA based on average of three, 5-shot groups measured by ShotMarker (65°F) 1857 FPS at target
1000 yards: 0.76 MOA based on average of three, 5-shot groups measured by ShotMarker (88°F) 1397 FPS at target.
(10mph variable cross wind gusts with moderate mirage).


Thanks for looking.
