Re: is this a good scope for a 338 lapua?

Sure, at 1000 yards you only need about 24 minutes, but the cartridge will do over 2000. You could have 80 minutes of drop at a still usable point. Depends what your needs are.
Some scopes have 50 minutes of elevation, some have 80+. Go for the latter even though you have a canted mount standard with the AR30 (I have one). I use a USO. One advantage you have, though I would not recommend skimping on robustness, is that the muzzle brake is quite effective, presenting less mechanical shock to the scope than an unbraked 30-06, let alone .300 mag. </div></div>
Actually, the reverse is true. You'll have more shock to a reticle with a brake gun because of reversal of recoil, meaning the recoil accelerates the gun reaward until the bullet passes through the brake, then the brake abruptly halts the acceleration of the brake.
This is why 50 BMG rifles are so hard on scope reticles...they have very little felt recoil but lots of acceleration, then reversed acceleration.

Hmm. Interesting. I hadn't looked at it that way. You think the reversal is that quick? I would have thought that it was slowed somewhat (in relative terms), more of a deceleration than a sharp impulse. In any case, all the more argument not to skimp on robustness.
