switching scopes

I'm trying to decide on a few different scope/gun options and combinations. I have a ruger 10/22 with a base mounted on it, I'm wondering how I can tell if this is a standard type base and whether I can switch a scope from a centrefire rifle to this one without changing the rings. At this time I have nothing to compare it to. If someone knew the dimensions of a standard centrefire dovetail type base that would be really appreciated.

I hope this makes sense
thanks

Some bases will take the standard Weaver scope ring(rifle) along with the 3/8 dovetail,( 22groved receiver) should be easy to tell Here's a link, find your base and click for details

Except for the smal traditional 22 scope ,all North American scopes are 1" and interchangeable with 1" rings.
European scopes are 30 mm(1.17 inch,) but I doubt your are using Eureopean rings and scope
Forgive me if this is not any help, I'm not familiar with the new stuff out there, havn't bought bases or rings in a very long time.

thanks for the reply. The scope, rings and base aren't new by any stretch atleast 15 years old. The scope is not 1", it's under, around .800". And the base is about 1/2" wide at the top (widest point), what dimension does the 3/8" refer to?

thanks for the help

North american scopes in 30mm are becoming more prevolent as well Hammer,,,Yet another gimmic (supposidly more light transmission) the 3/8 he was referring to is the ID of the dovetail not the OD. If its just 15 yeas old...A standard set of weaver rings should fit that base from what you are describing

Here's an article that gives good definitions of terms,base/ring comparisions for weaver and ohter manufacturers and a host of links to scope accessories.
