Hi tony, lol always the way mate, next time you go, leave your wallet at home..
the webley MKVI are lovely revolvers aren't they, if im honest they are not my style in looks but i cant fault the realism and build quality thats for sure, i personally think they are the best airgun revolvers on the market for those reasons..
As for pellets RWS Co2 Target pellets work well in them. 7gr with thin smooth skirt, lol worked well in the one i used anyway, and in general i love those pellets anyway in pistols and revolvers and even in my walther lever action rifle..
Happy shooting mate.
ATB, Marc..
