I have low Leupold QRs on Remington 7s and 700s that have Leupold 2-7x33s on them and they clear the factory contour barrels fine. I mount my scopes farther forward than some folks, with the rear of the read ring just a RCH ahead of the magnification adjustment ring on the scope. I you mount your scopes farther back, the scope's objective housing/bell might touch the barrel shank.
My old brain totally blew off how where the scope would be mounted effecting ring height needed. My apologies. To me.......there is only one way that will work and it's been that way so many decades I forget (not a lot of rifle shooters in my neck of the woods) others use different, but correct for them, scope positioning.
I thought about emailing Leupold service or even Midway about ring height since having one in hand to compare isnt an option.
Habitually, my scopes are as far back as they will go and short scopes sometimes require an extension front ring. (Thick shoulders and short arms. #akaFAT.
) It's been this way since I was in my teens and weighed 160lbs though. I'm not a stock crawler either. Short neck. If I can't close my eyes, mount my rifle, open my eyes and see perfectly though the scope........I change it.
Not at all saying this is the "right" way, it's simply the way that works best for ME. I can say that this method allows me to mount my rifle and shoot very rapidly if I desire. Next deer will be No 100 and a good many of those were shot at semi-close range and offhand. There simply is no time to find and use a "leaner". It's also a manner I do considerable amount of practicing.........for obvious reasons. Without giving distances, for fear of those who seem to want to point fingers, I will/can/have shot deer at longer ranges shooting offhand.....than what I see suggested online.
The rifle stock........and scope location has to be more than "close" for me, or I won't hunt with it. (picky old fart, huh)
It wont surprise me at all if with the same 2-7x33 Leupy........I'll need a front extension AND higher ring. I guess if I order a set too low for me........I could post em here on the 'fire though.
All good info, guys!
All of it will help me make a choice.
God Bless
