Posting an update...
Played with the scope for a few hours. Still some questions....
TLDR: seems to track appropriately. But *might* have slipped/skipped adjustment during the nrl and moved zero up 1/2". During this test it *seems* to have shifted back to perfect.
Same ammo from the initial zero and the nrl. 140 hybrids. Remembered my br4 this time and it was 98 yards (at a different shooting range then my initial zero, forgot my RF at the indoor range).
Started with a tracking test.
Aimed at top of the black post. 1 shot each at 0,1,2,3,4,5 mils. Then repeat for 3 shots. (Green circles)
Probably did it in 20 minutes. So barrel was getting a little toasty.
0 Group was 1/2" high.
First two shots from each group lined up great. On the third pass At 2 3 and 4 mils it dropped low (single holes circled orange). But at 5 it was close. Those groups at 2,3, and 4 are the largest that gun has ever shot.
Range went cold. Possible sources of uncertainty. Barrel was getting pretty warm (i was pausing intermittently, but still...). I was shooting off of a wiebad bag, And i didnt notice that the mdt triple pull Had started to click out. Probably halfway out on the first leg each side.
Came back and repeated the test going straight from 0 to 6 mils. Zero now hit the post. 6 mils up seems to be accurately adjusted. (Orange groups). measured everything at home and its tracking within the margins of the groups. And the 0 to 6 is almost spot on.
Went to the ocw target and shot 2 hybrids. Pretty much dead on zero.
Ok....did my scope skip some clicks? Or is it slipping? Not sure.
Range cold. Let it cool off.
Shot some load dev. 144 gr lrht's. Shot lights out. (The one flyer at 42.3 was me rushing to get some shots off just for chrono data, forgot my chrono, and some old timer let me borrow his but range was about to go cold).
Range cold.
Down to my last few 140 gr rdfs that I need to empty out.
Shot 2 for zero at the #4. Moved right to the #5, Dialed 10ish mils up, back down to 0 and shot. Repeated 3 times. Seems good. (Pic above).
Tried a 0 to 6 mils test with the rdfs. Seems pretty spot on except for one that dropped way low at 6 mils. No explanation there.
Conclusions....
My zero was .5" high initially. That may explain my high misses at the nrl.
But during the test it sure *seems* like something settled or shifted and brought the zero back to perfect (where it was before the nrl). My initial tracking concerns at the indoor range are likely due to the target not being at 100, and me not ranging it. If it was at 98 yards that would explain my perceived tracking errors.
The 144s shoot good
Uncertainties....
definitely ran it a bit hot
ckyepod unclicked on me unnoticed during the berger hybrid tracking test
barrel has ~2000 rounds on it, mostly in NRL context or prep. And maybe 750ish berger hybrids and I havent touched that load so maybe its shooting out or out of tune?
My electronics at the NRL may have just been really wonky due to the cold weather and negative DA and it being the first time i used them this year.
Im going to check/tighten the turret screws. And check the action screws. Load up a bunch of ammo and go to the next NRL. If it seems wonky on the practice range I'll use my 25 prc instead.
