I have a Savage 22-250 on a borrowed condition which has weaver mounts and an old hawke 40mm scope on it on low mounts. I'd like to try my 50mm tasco (25mm tube) to see how it performs before the 30-06 arrives but the mounts are too low.

How do you measure the mount height to know whether I need med or high mounts before I buy some? I thought about playing safe and just getting high but also read it's better to keep the scope as close to the barrel as possible, is this true?

It also has a T8 mod & neoprene cover and can't understand how you can still see through the scope, as it is so low it is half obscured by the mod, etc at the moment??!

If anyone has a set I could buy once I know which ones are best please let me know too,
