Blimey you can get an awful lot for 600.
S400 secondhand 250 -300
Small dive bottle 80
Small scope say 80 mabee less for a sh panorama
Shooting mat 50 new
Shooting glove 25
Add a load of pellets , some money for bottle fills , and a few days money on a range.
Easy sub 600.
Altho for ft you need generally quite expensive scope.but I'm not hugely familiar with the discipine.
