Ok, have a good load worked up for a new Seekins 6.5 Creedmoor, shoots 0.6 - 0.8 MOA regularly with a muzzle velocity of 2815 fbs. Using a few different ballistic apps, all were in agreement that with 130gr ELDM I should have a 9.4 MOA come-up at 500yds with a 2040 fps impact velocity.
Today was its trial run at 500yds, the good news is that group size ranged from 0.8 - 1.0 MOA at 500yds, its been months since I have shot at that range so I was reasonably happy, another piece of good news is that my impact velocity was spot on (our range has a chrono at the 500yd target).
The puzzling thing is that dialing 9.5 MOA put me a full MOA high (5"+), I dialed back down to 8.5 MOA and that put me where I need to be. Now I can "tune" the apps a bit and make reasonable adjustments to for .1-.3 MOA change but a full MOA would be huge changes to velocity, bullet BC, etc that just doesnt make sense.
I am left wondering about my scope, its a Zeiss V4 4-16x44, havent shot this paticular scope at distance before this, it was purchased as demo from Red Hawk
Is my scope where I should be looking or am I missing something obvious (which I seem to do frequently).
