I'd personally look into investing in the NXS
line from Nightforce. They are as tough as they come and a 338 LaPua recoil to them is nothing. NF has a 5.5-22x
and a 8-32x
that fit right into what you need. If you want to work out to 100-1200+ yards, the 5.5-22x is a great choice. If you want to really stretch out to 1500+, that 8-32x might be a winner. You're getting excellent glass, some of the best coatings available, and a tough constructed scope with reliable repeatability, a HUGE factor in shooting 1000+. I like the MLR reticle for most applications, but Nightforce does give you a Selectric.
