I agree with Kraigwy's comments on Weaver Model T's. I've used their T10, T16 and T20 scopes and were probably the best buy for the money.
But Weaver only makes T24 and T36 ones these days. So, I suggest a Weaver V series 4-16X which I used on a custom .300 Win Mag and it did nicely on 1000 yard targets.
Most of the money on high dollar scopes pays for the optics that maybe 1 in 1000 will benefit from. It's not necesary to count the eyelashes on a pasture poodle 876 yards away. Besides, if the temperature's above freezing, the heat waves will blur them anyway.
With whatever scope you get, mount it on your rifle then put an optical collimator in its muzzle. Adjust the scope so its reticule goes onto the collimator center reference. Move each adjustment two clicks off in one direction then back two clicks. Do this again but use only one click in each direction. If you use a binocular half to look through the scope, that'll magnify the image and make exact placement of the reticule on the collimator reference a lot easier and precise. If the reticule ain't exactly on the collimator reference where it started from, send that scope back to its maker and get another one or a better one.
"Boxing" shots on paper to check a scope's repeatability only works well when the rifle, its ammo and the shooter produce no worse than 1/10th MOA groups; every single time. So, boxing shot holes is a waste of time, ammo and barrel life as far as I'm concerned. You're not going to get good data on a scope's 1/4 moa clicks with a rifle-ammo-shooter system that shoots 1/2 MOA at best. The "yardstick" needs smaller graduations than what's measured to get good information.
In order to use most of your scope's adjustment range in elevation, you'll need a sloped base to mount it on. 10 MOA through 30 MOA bases are available. I suggest that if your scope has a 40 MOA adjustment range, a 10 or 15 MOA rail is best, then you've got some wiggle room should the barrel axis not be perfectly aligned with the scope base axis. But you'll end up with somewhere around 30 MOA of use in elevation with a 15 MOA rail.
Good info on scopes...
