OK guys, I think we have jointly worked this one out. I do not need taller rings, and the regular 41000 base should solve the issue of match up, and allow room to set eye relief. I just hope this things shoots good enough, when everything is finished, to make the grade. I've never shot a large caliber bolt action rifle at an animal in my life. A friend who hunted with me last year, made me an exceptional deal on the rifle as a thank you, and I bought the scope from a TNDeer member, after another friend bragged about how his was so great in low light. I am not known for setting out there until I can't see anyway, so this is really just going to be another cool toy! Thanks to all who responded.
