Any tips on becoming a better aim?

[Scythe13]

As SD and most the guys from the Dartmoor trips know, my wife is a crack-shot (I hate her for that).

Her recommendation, shooting sticks. Shooting from prone. Shooting off a platform. Learning about windage (probably not important at 20meters, but I only asked her a basic how can I become a better shot question). One thing she recommended, that really threw me out, get a coach, if that's not possible get a camcorder and record yourself shooting. This should highlight problems with your technique.

That's the best I've got from her. Hope that helps.
