Hey diver1488,
I have a Walther in .25; I checked your location to see if you were nearby, I would offer to let you shoot if it were convenient to you.
As you, I studiously read the threads prior to purchasing, so I can offer....
The Patriot, Falcon, and Hatsan are all made by Hatsan (no surprise).
The Walther reports stock splits after a few shots; remedy....remove the stoke screws (they are counter threaded) clean and reinstall with loctite, wait a day or so depending on temp and humidity prior to shooting. This is standard advice among the heavy recoiling centerfire circuit folks. And it worked for me.
Dont bother with the two-piece scope mount; buy a one-piece mount from the outset...mine is an accushot and it is working for me.
pellets are an issue that I cannot advise on as yet: I have about 300 thru mine and so far it hasnt liked crow mags or silver stings, it does like eunjin'spehaps as they are tight fitting; it is too early to tell for me.
It wouldnt group at 10m initially; 200 rnds later it groups at 18m, but not bug splat reliability.
It smells when you shoot it!!! so )being a chemist I decided to try an experiment, I would shoot and then take a hypodermic and extract the supernatent air from the gas port) extract does smell but I dont know if it reduces the dieseling at all. Kinda cool experiment tho eh?
The scope that came with it isnt up to Leaper standards but it hasnt broken FWIW.
It is enjoyable to shoot as it a tru beast.
For me it was worth the $
