@wombat13 - if you’re changing frequently and especially if you’re doing so in the field, then QD’s make sense. However, it sounds like you won’t be changing frequently, since you mentioned one of these rifles doesn’t get used 350+ days per year, and it doesn’t really sound like you need to don and doff in the field…
So personally, instead of buying QD mounts, I’d simply buy a torque limiter stick or torque driver, and use the conventional rings on both rails. Naturally, this will mean you’ll need a pic rail on both rifles, which isn’t as elegant on the Ruger as it is on some rifles, but the parts are out there.
I pull my scopes from my match rifles frequently, I’ve even had to do so in the middle of a rifle match - and installing in the same slot and torquing back to the same torque brings my zero back. I’ve also transplanted my optics many times from one rifle to another, such as shooting a night match which requires illuminated reticle and swapping out a non-illuminated optic for the match, then returning both scopes to their previous rifles again after the match. All just using standard pic rings and rails.
I do have a couple scopes on Alaska Arms QD mounts for Ruger integral bases which I use on the same rifle, a 1-6x and a 4-16x, so when I change barrels from 300wm to 458wm, I can swap scopes quickly, but also because the 458 barrel has iron sights and I might remove the optic in the field. But that’s a little different paradigm than you’re describing, and obviously the Ruger compatible rings I’m using wouldn’t work for your Kimber.
