thanks for heads up....got 2 of each
I ordered 2 of the 25.4mm = 1 inch.I plan to use them when mounting scopes to make sure the vertical cross hairs are vertical.If I put the vertical cross hair on the vertical corner of a building and the level bubble is centered, then the scope is aligned correctly. WAIT a minute. That tells me if the cross hair matches the bubble.Someone please tell me how to make sure the vertical cross hair is aligned vertically with the gun?How many inches would the point of impact change in 50 yards if the scope was changed 5 degrees from vertical?Use a muzzle velocity of 800 fps.
