I'm not much of a shot, and I have been spared the bench-rest affliction, but here is part of a post (#119) from a guy over at RFC with a very good accuracy report:

Fellow AAR Owners, my first range test.
Trigger spring removed, pull now 1-5/8 #
Action screws torqued to 12"# This setting may be too low. It's just where I decided to start.
Bore polished w/ J&B. 12 slow, careful strokes
2 each Weaver #16's lapped to match contour of AAR receiver
Burris Signature Zee Rings (low)
Weaver CKT15 15X (Japan) Duplex reticle
+ & - .020 inserts sideways in rear ring to bring scope to intersect w/ the bore (within 8 clicks @ 25 yards)
weather: 85 degrees, wind 12-15 MPH switching 180 degrees every few minutes.
The footprint of the firing pin is small! Every round went bang; but I would still like to see a bigger pin footprint...
You get my setup and my groups, the good, the bad and the ugly. No cherry picking. This is only the beginning for the AAR
Start shooting @ 25 yards.
This is how I shoot. I have no idea how the "Experts" shoot...
5 rounds to finish final zero, then I put 25 rounds of fed automatch (old lot)through the AAR as fast as possible.
The more rounds I put through the ARR, the closer to center the shots moved. Either the bore was slicking up some more, OR, the AAR just likes a lot of bore dressing. Or???? Any guesses out there.
First 5 shot, 25 yard group automatch (as I dodge the wind watching the flag & probe do a disco dance)
Second 5 shot, 25 yard group automatch
Barrel cleaned w/ patches, brush & solvent. 10 shots of Golden Eagle match to dress the bore (no pic saving pic count).
First 5 shot, 25 yard group Golden Eagle match
Second 5 shot, 25 yard group Golden Eagle match
again, more rounds down the bore, things tighten up. dressing?
...Not too bad for a first outing! Still a lot of work to do! I have to increase torque on the action screws. I need some better wind conditions. or lack of wind (fat chance that ) I think the barrel is slowing slicking up.
Best Regards, ultramag44
