I have the 50s in .22 which I bought recently from Holland.

If only your UK dealer had bothered to ring you back or tried to compete with the European dealers?

What a super little rifle!

When you fit the 16j spring, be prepared to give the rifle a re-lube and a fettle and if it's anything like my one was; I had to cut a few coils off the spring to keep it under 12 ft/lb. (I fitted a TinBum kit, a delrin piston liner & polished the piston). The recoil is great and it just makes a gentle 'thump' noise. Straight out the box it was a bit twangy & crashy.

Mine likes RWS superdomes or Crosman Ultra Magnums, both of which can be obtained really cheaply.

I have a hawke 2-7x32 AO IR scope on mine to keep the weight down.

Much less muzzle flip etc than my HW95k.

I hope you enjoy your new 99/50s

Ouch!
