[QUOTE="Pdvdh, post: 1434411, member: 4191"] Have you checked POI also. I did this with 5 different rifles last winter. Good way to collect Temp Vs MV data. I ensured the rifles and ammo both came down to ambient temps. I ran the tests down to 0F, even though I don't hunt in those temps. RL 33 was good until the temps dropped below ~25F. But the #1 lesson for me was the minor POI shifts from routing outing to routing. I did this over about a 4 month period of time. Not large POI shifts. One scope click was pretty common @ 300yds. 2 clicks was not uncommon. Learned either the lighting or the temps or both, contribute to minor POI shifts with my rifles. One rifle was more stable than the rest. But not immune. All custom rifles. And to clarify, I mean most every outing, which was normally different weeks, temps, and lighting conditions, I observed minor POI shifts with most all rifles on paper at 300yds. [/QUOTE]
