My 280 now has updated optics. Here's a couple pics.
I sent the scope back to Leupold and had them install M1 knobs and mil-dot reticle. If you have Leupold scope and you want to consider having Leupold do some upgrades for you - they do a great job. The new knobs and reticle in my scope are great. The adjustments are reliable and repeatable. The new reticle is crystal clear.
Also, the rings and bases have been upgraded. I changed from the standard Leupold two piece bases with medium rings to Burris Signature Rings and Bases. The rings have the plastic inserts so the scope is canted +30moa. It's a great set-up that is rock solid.
I have also begun to do some reloading for this rifle (can you find primers?). It continues to shoot pretty well at .75 moa with a load of Fed210 primers, IMR4350 and 150grain Sierra Game Kings. From previous testing I know this rifle is capable of .5moa, so load testing will continue.
