Any Feinwerkbau, Walther, Anschutz Owners ??

I've owned Anschutz and Steyr target air rifles, and they are both excellent. As mentioned, service and parts availability can be an issue. At one time, Anschutz USA handled both Anschutz and Steyr air rifles, don't know if that's still the case. Pilkington handles Steyr, but I think his specialty is 10 meter rifles. They are all typical, top shelf German workmanship, but I would inquire about service and parts before buying. 
 
I don't have personal experience with the Walther and limited experience with the Anschutz but can tell you to be cautious . They are a delight to use, for sure. What I'm referring to in terms of caution is the 2 piece breech block design. When Fwb came out with the P70, ft shooters jumped on them and had them bumped up to the 20 ft lb area. They are designed to be used indoors in a somewhat controlled environment and when exposed to large changes of temp, could get large poi shifts. The Steyr can be free floated, so eliminates that problem. Fwb continued the same design with the P700 and P800. Just look at whether the scope and barrel mounting are one piece. Shouldn't be a problem , if so.

There have been a good number of people coming up with ways to address that and some may have been successful. Some research may be necessary here. If you look back through the AAFTA history, you can get a feel for the probability of success . For such fine rifles, not many have placed well from my last look.
