Thanks for all your comments, there seems to be a lot more to pistol shooting than I thought.
Seems that the underlining trend is to join a club. I know that there is one in Kings Lynn, so thats okay as I work in Lynn.
One other question, what pellets should I use? I know that each rifle / pistol prefers a different type of pellet, but what weight, shape should I be looking at. My HW100 loves AA field 8.4 , do pistols prefer heavier or lighter pellets, or is it a case of suck it and see.
Sorry, also, co2 capsules, what the cheapest way to buy them, I've seen them on the bay 50 for around £20 ...j Ramsbotham seem the cheapest...are they all the same?

Thanks again
