Re: thoughts on leveling a scope and bubble level
Given that your alignmen is off at 50 yards, I would definitely start there. A half inch off at 50 yards could put you off near a foot at the distances your shooting. Also, are you compensating for spin drift? I have found the best way to confirm the alignment is to shoot a plumbed verticlal line at 100 yards in 10 MOA increments, 5 shot groups. Based on that alignment, it would adjust my scope and level. It's also a good time to check scope tracking accuracy as well. IMO.
