Question #1 - you indicate these are the .451's - did you get some .458's?
Question #2 - which stock do you have on your Omega? the laminated wood or the synthetic? If it is the synthetic then the warming barrel and stock pressure can/will move the POI... but there is a simple fix.
I Chrony'd all five shots. Chrony was 9 paces from the end of the barrel.
1902, 1921, 1921, 1915, 1912 FPS, 5 shot Average - 1914.2 FPS
That is right at what I am clockingwith 110 grains... I am at1920fps ave. Elevation could make some difference - what is your elevation? I am at 2600' above sea level.
The 3 shot group circled was shot through the chrony at 100 yds and yes the chrony survived[8D]. Point of Aim was the red circle. I didn't want to tempt fate with the way the wind was blowing so I stopped at 3 shots. Numbers are; 1555, 1580, 1573 FPS @ 100 yds Average - 1569.3 FPS
Nice to see these numbers - I have never shot over the chrono @ 100... I'll plug your numbers in the Barnes calculator and see what it comes with... Really close the calculator says 1590fps @ 100 and you are measuring 1569.3
With your 200 yard shots... you have a dead animal you are within the 6" circle that I often refer to from your POA.... GREAT! you gotta love Noslers... but they do cost money...
Congrats....
