Some of the guys on the savage muzzleloading board have busted luepolds on hotrod loads, no one has ever busted a conquest, with lots of tries. That said, luepold is very good about replacing busted scopes. A guess someone will have to figure out a way to break a zeiss before we can find out about the customer service. I am a burris/nikon man myself, no point in spending all that money to me. I believe the burris fullfield II is the best $200 I ever spent! Ask me again in 20 yrs and I will know for sure.
