buy the one youcanthide...... Has for sale mate, £20.... Nice shape to start with, get some 9.5 mm steel bb's from ebay, and just shoot the shit out of it! Start at a distance of say 5m until you feel you getting the hang of it, always pull to the same point (anchor point) I.e cheek, ear eye etc.... Then find a point on the catty to use as a marker, I.e top of left fork, right fork etc. once you find you anchor point and aiming point, stick to it!!! until it's lodged in your brain, your muscle memory will then just naturally make you shoot that way, don't take long mate, you'll be filling your
