RE: low, medium, or high rings??
as low as possible.........i had 2 excelent shooters that won many awards and been shooting all their lives tell me to keep my scope as low as possible for the best accuracy......keeps your head planted down on the stock and that means a better shot......and the higher the rings the easier it is to bump the scope and move it ect.....thats why if you post about see thrus many people will tell you not to use them........i killed a deer running full speed at 20 yards in a thicket with a 3x9x40......it was like having a crosshair on the deer as it was running......when it got into a clear spot i let one fly......piled up in the air and fell down.........i had it on 3 or 4x like i always do being my shots are typically 30 yards or so........ive never had a scope hinder me what so ever........but i got a 40mm lense......that makes it nice and on low power its not like your looking through a scope......good luck with whatever you choose
