Re: Need help with ring selection
I just mounted a Schmidt Bender PMII 5-25x56 scope on a Savage 110 BA.
After futzing around for about a half hour with a friend who is very learned on this topic, we'd decided on Ken Farrell 34mm standard rings. After he left, along the lines of measure twice, cut once, I took a stack of quarters seven high to get the same height we'd calculated by using a machinist's rule and a couple of sharpie pens (used the barrel thickness). I don't do this often enough that I'm comfortable with the process, obviously. I then took one quarter off, measured the stack thickness again, said "close enough" and ordered the set.
Rings came, everything bolted on, and there is enough room below the bell of the objective (with flip-up cover) that I can slip a dollar bill under it and the fore-end of the long-ass rail Savage puts on this gun.
Get the gun level, put the scope on a stack of quarters at the height you want, measure the stack, that's the ring height rail to bottom of scope give or take a few thousandths, but we're not building Mars polar orbital landers here.
Modeling clay can work, but it'll deform some, stick to the rail (you did use saran wrap?), compress when you dial down a caliper, but it'll work, depends what you've got on hand and can measure.
