I posted this follow-up on AR15.com. and though you guys might be interested in an update.
Yesterday was real cold (like 20 degrees), but it was sunny and bright, and I had enough time/daylight to slow down and concentrate, and practice better breath control and natural point of aim. It absolutely showed up in the groups--which give a much more precise idea of where the scope was tracking.
There is some red meat for the haters, though--tracking got flaky to the right at 15 MILs. This is something I will explore after I load some more ammo (and my nuts have thawed).
NOTE: Right And Left tracking tests on both days resulted in what appeared (I think erroneously) to be a right hand bias in the tracking. After consideration, I went back and measured both sets of R/L tracking tests. The groups are almost exactly 9 MILs apart in both tests. I noted that my measurement were taken from a theoretical center line, not from the center of the 10 MIL/15 MIL UP groups impacts, which on both days also showed an apparent RH bias.
On reflection, I'd say that the most likely answer to consistent POI bias on 2 separate targets is that the scope is canted in the mount.
Here is the update I posted at AR15.com:
I had a chance today to do some more testing. I used a bigger sheet of cardboard, and was able to dial up 10 and 15 MILs, then Right 4.5 and Left 4.5.
I was able to replicate (and explore) the flaky behavior of the Right windage, and even induce some erratic tracking at 15 MILs up and 4.5 MILs Right, which I want to explore some more, just for my own curiosity. It doesn't alter my perception of the scope at all--I did not buy this scope to shoot at 600 yards in a 30 mph crosswind while dialing corrections--but (that being said) don't believe anybody who is telling you that you are getting a Razor Gen 3 for $500, because you are just not. That is not a knock on ARKEN, I am very impressed with what ARKEN is offering here, seriously, what the fuck, dude--this scope costs $550 , $400 if you subtract the cost of the free accessories, you are getting a damn good piece of gear for the money spent, and maybe even for twice the money. But again--be realistic. Don't buy the thing and send it back wanting a refund whining like a cunt that the windage gets flaky at 15 MILs when the erector hardware is at a hard stop bumping up against the fucking turret housing. I mean--no shit.
I'll post a couple pics of what pleased the shit out of me after a long shooting session in 20 degree weather.
Box Test To 15 MILs by
Eight Ring
After wrapping up the box test there was still some ammo left so, I tested return-to-zero--dialing UP 15, Right 4.5, Left 4.5, Down 15, and broke a shot.
Return To Zero From 15 MIls by
Eight Ring
I thought it was a fluke, so I did it again--UP 15, Right 4.5, Left 4.5, Down 15, and broke another shot.
So I did it again by
Eight Ring
What can I say--it kinda felt like a gift after freezing my nuts off in 20 degree weather all afternoon.
Below are some pics documenting the tracking data. I still have not confirmed that the range is 100 yards, but I'd guess it is close to.
10 MILs is 36 inches at 100 yards. There are 6 shots recorded. 3 shots on the way up, then I went to 15 (Up 5 Mils), then Right 4.5, then Left 9 (4.5 to center, 4.5 Left), then Right 4.5 (to center), then Down 5 (to 10 MILs elevation)--then added 3 shots to the first group.
10 MILs 6 shots by
Eight Ring
15 MILs is 54 inches. Yes that's 3 shots. Apparently my rifle likes cold ammo and 20 degree weather.
15 MILs Elevation by
Eight Ring
All told it was a good day, and I am a happy camper.
Ah--as I review the post the pics of the Right and Left tracking did not attach. I will get those posted as well.
ETA: Right/Left Tracking data:
15 MILS LEFT AND RIGHT by
Eight Ring
The wind was gusty, so I shot quickly because I was afraid the target might blow down.
The group was wide(r) right than 4.5 MILs, I figured it was the wind gusts, and I re-shot. Same results.
RIGHT 4 pt 5 MILS by
Eight Ring
2nd group/3 shots at 15 MILS elevation/4.5 MILS RIGHT:
Right 4 And A Half MILs by
Eight Ring
And that group tracked MORE than 16.2" RIGHT, and it did so consistently.
4.5 MILS LEFT/15 MILS elevation:
LEFT 4 And A Half MILs by
Eight Ring
The 4.5 MILs Left group tracked shy of 16.2" left. Interesting.
I will shoot some more tests soon closer to the optical midline, to see how Left/Right tracking does there.
All the best.
