Thread: Buggar... scoped moved

First question, has the scope moved ? or are you just considering it as a possibility. If it has moved then re tighten and have another go.
typing too slow. Oh right then in that case screw it all down good and have another go with the current loads you have

Scope 100% moved. Saw the original mount marks, and after the 50 the scope was at least 20mm difference.

PITA for sure - though to be thorough and sure - I'd start over with the seating testing... cant be left 2nd guessing then, and you can then graph your results and this will indicate where ya nodes lie - 1 vs 2 tight groups etc... then helps lock in a seating depth that allows for wear...

NFT, that's a tour de force.
Looks like a 6mm PPC ?

I don't like the idea of fitting a single curvy line that runs exactly through all the points on your graph. A regression curve that allows for some uncertainty of measurement in each groups size would be more convincing. You can get some idea of that from the way your 3 group average varies by up to 0.2" from the single measurement on the left. Looks like around CBTO 1.915 should be your sweet spot. Nevertheless, very good work and I wish I had data like that.

The graph was plotted using Excel - using exact figures. I hear you though not keen on use of a regression curve - we OCD over collection of such results, change seating depths at three thousandths of an inch at a time - there's no way I'm going to use a regression curve to draw a 'best fit' - its either doing something or not - thats my view that may differ from others.
However I'm more OCD on these sort of things! Can be a hinderance in some aspects !

Thanks though.... you too can attain data like this...
