I use a Hawke 8-32X56 scope with FX adjustable rings for long range. Without the adjustable mounts I would run out of elevation adjustment by 100yds.
Good to see you got it figured out. Wanted to throw my two cents in for anyone that might read this thread at a later date. My favorite scope for long-range is the SWFA 12X42 Mil-Quad scope. The scope has a very precise etched glass reticle complete with mildots. The cool part is that it also has milliradian turrets so you can read the reticle like a graph. This makes it so much easier to just dial the turrets rather than use holdover. Which is way more precise imo.
