Zeroing:
Scope was mounted as standard with a Geissele Super Precision mount. The rings were degreased and installed with 65 in-lbs on base screws, and 18 in-lbs on ring cap screws. The baseline 30 round group with this lot of ammunition was 1.3 MOA at 100 yards.
Biresight, fired 1 round, adjusted. Three, adjusted eight .3 mils, then 3 rounds in center dot.
Drop Evaluation RTZ and “Tracking”:
For an explanation see-
Scope Field Eval Explanation and Standards
The “test” consists of three 18” drops on a mat- one left/right/top with a shot to check zero after each drop. Then the exact same thing repeated from 36”. Then three drops on all three sides for nine drops on the last part- 15 drops total. This is not “abuse”. The 18” drops are a joke really. The 36” start showing something. And when a scope make/model consistently goes through the whole thing without losing zero, and makes it through the high round count portion, failures in actual use are almost unheard of.
This one was conducted on semi packed soil.
Right side 18” drop shifted it right. Then sort of came back. Shots are as marked.
Torqued ring cap screws right hand, probably 28’ish in-lbs.
Fired 4 after tightening-
Adjusted down .4 mils, and conducted 2nd drop eval. No issues this time.
RTZ: no issues.
Adjustment (tracking):
The second box of ammo I had was a different lot number. The zero was .1 mil right, however the far right shot was from barrel mirage- it was nearly 30 rounds fired in 5’ish minutes.
Conclusion:
After getting the rings torqued correctly (once again), the scope functioned as it should. The turrets are not revolution indicated or marked in anyway, and I spun to the wrong revolution twice during the adjustment portion. The turret does raise and lower in the stem, so there is no reason for them not to mark it. I scratched a line to indict the zero rev.
It’s now mounted an AR15 and will be tracked as usual.
