Not exactly the same setup, I have a Marlin XLR in 45-70 with a Weaver Classic 1-3 scope. Straight tube no bell.
With a Leupold 1 piece base and medium rings it's a little tall.
.375" base thickness.
.642" between barrel and bottom of the scope.
It puts my eye higher than I like so my cheek is a little too high on the stock. Higher than with sights for sure.
I need to go with "low" rings.
I'm not sure how tall the Q.D. bases are, if they are shorter so you can still see the sights when the scope is off?
Nice cartridge choice,Good luck with your setup!
Talley I just ordered these.
