I agree with Quick, That's FINE!!!
Its best to get them as close to the barrel as possible. With that scope the hammer is the limiting factor. My all time favorite BTW, I have one on almost every hunting rifle I own, nice choice!!
Here is a PIC of the clearance I get with that same scope and Leupold PRW MED rings. The first one is my 500 S&W the second my .243 Ultra.
Thought I had a pic of it on mt 25-06 Ultra, but cannot find it. Its identical to the .243 anyhow.
