RE: Zeiss
All scope makers build an occasional dud including Leupold.I wouldn' t be afraid to bolt any premium scope on a heavy kicker to see if it holds up,life is too short to wait for a scope to be proven.The good scopes all carry excellant warranties and the makers will replace with another if you manage to break one.I know of several 458' s and large caliber weatherbys that have Conquests on them and they are holding up well.
