Call Leupold and talk to them about a scope for the 458 LOTT. They will probably recommend one of their SHOTGUN scopes. That is what they recommended to one of my buddies that has "trashed" a couple of 1.5x5's on a 416. After a long discussion with him I am not sure if it was the recoil or the "ride" on his 4 wheeler that did the scopes in.

However the SHOTGUN scope did not break when used under the same conditions.
