Re: Bausch & Lomb
total internal elevation adjustment is 20 MOA.
Unless you have a tapered mount and/or adjustable rings, and/or perhaps a mil-dot reticle to utilize for holdover aiming, you will run out of up very quickly, perhaps even not much past a 100y zero depending on your rifle receiver/base/ring setup.
Good optics, and very long scope. But certainly there are much better choices for longer range shooting due to its limited internal adjustment.
it's not about need in the USA -- it's about WANT
