Glad you are pleased with it. As a former owner of both the HC and Mk 3 variants, I agree with most of what you say except I did find the beartrap ratchet a bit annoying and the click-click-click noise as you cock I suspect could frighten rabbits away. Personally I find the cocking effort ridiculous for a 12 ft lb rifle-my Weihrauch HW95 is cockable with one finger! I don't know whether you tried the TX200 Mk 3 before choosing the HC but I found the slightly longer cocking lever much easier to use and the extra length hardly noticeable. The mk 3 is also quieter-unless you use the screw- in extra silencer which completely ruins the whole point in having the shorter HC.
Good shooting!
