I would go 400 as well, or even better a second hand MPR 400 which has a slightly better barrel for withstanding zero shifts from light knocks.
The 400 or 500 series are probably the most reliable gun out there for hunting or HFT. I have had most of the other guns available including a HW100.
I agree with the other posts about buying elsewhere, but I would go second hand, preferably from someone on here or a club.You will probably pick one up with a suitable adjustable custom stock on as well which will be a bonus for HFT.
Panorama is a good choice for the money but make sure you get the 40mm front (not 50mm, as its easier to mount) preferably with adjustable objective.
