I installed my recently received Proof Research 20" barrel into an Aero Precision enhanced upper with a Maxim bolt, put it on a rifle lower and went shooting today. It's a shooter. Today was for checking function, scope zero and playing with my new Labradar.
The barrel shoots great. No problem shooting sub MOA groups without trying too hard.
The Labradar worked great. What an awesome chrono. It picked up every round fired. It can even download shooting stats as a spreadsheet.
I shot Hornady factory AMAX and ELD Black. I also shot loads with 27.6 grains of AR-Comp and tried a new load of TAC. Both behind the Nosler CC bullet.
My only real surprise today was the velocity of the AR-Comp load was about 50-100 fps higher than I expected at an average of 2580 fps. For those interested here are the velocities I got today with the Labradar.
Factory AMAX - 2491 fps
Factory ELD Black - 2482 fps
123 Nosler CC, 28 gr TAC, 2.255 OAL - 2467 fps
123 Nosler CC, 27.6 AR-Comp, 2.255 OAL - 2580 fps
