Yeah, okay, so I get to the range and the wind is only ::) 'bout 12 - 15 mph, and my flag is only moving through about 45 degrees, so it's not too bad for West Texas conditions.
I set up my gear. I have a target posted @ 25 yeads, and adjust the objective on the Weaver 36X for that distance. I remove the bolt and boresight the barrel on the target. Looking through the scope, the vertical alignment is just about perfect! :) WOOTZ! :) (last night I had zeroed both scope turrets and put 0/0 inserts in the Burris Signature Zee rings).
I have some pulled, GI 147 grain NM bullets for barrel break-in. 43 grains of IMR 4064, bullet .003 shy of rifiling. Remington 9-1/2 primers. Loaded on Bonanza Benchrest dies, Redding Ultramag press. New Winchester brass, trimmed, and inside of case mouths cleaned up w/ a 30 degree reamer.
One-shot & clean routine w/ Barnes CR10 and Shooters Choice, but getting almost NO copper! ;D WOOTZ! 4 shots and I switch to 3-shot & clean groups. Getting very little copper. Bore is slickier then greased glass!

Group is center, but 1.5" low. I'm thinking I'll need + & - 5 inserts for 100 yards. Wind is getting downright ugly! :( gusting, and flag is swinging through 90 degrees and the shear is bouncing up now.
100 yards. Switch to 168 Nosler BTHP match bullets. Group is 6 inches low. Put +5 insert in borrom of rear ring, -5 insert in top of rear ring. Groups seem to be tightening (I'm doing 5-shot & clean now).
Here's 2 each 5 shot groups upper one is after insert change. Lower one is tighter (I made an adjustment of a few clicks to bring the group down).

I had 2 instances of the accu-trigger 'clicking', but no bang. Both times I just reset the bolt handle. I did not change the adjustment from factory setting.
The rifle sits on the rest and returns to the correct place as the rifle slides back & forth. Almost no felt recoil! :) I got used to the 2-port system fast! 8)
I have load development to do now. My overall impression: I LIKE! I'm glad there is one factory that still takes accuracy serously!
