If you want a change you could always try Practical Shotgun but it will mean getting a 5+1, 6+1, 7+1 or 8+1 pump or semi-auto shotgun, you could just do it with a 4+1 (a new discipline is a damn good excuse for buying another gun for the collection )
.
I used to shoot this when I lived in the UK but as yet haven't found anywhere local in New Zealand that does it.
If you don't know anything about it have a look here : -
from the British Open 2011
Normally shot at steel plates with Red "No Shoots" amongst them that cost you points if you hit them.
As a clay shooter I find this discipline far more rewarding than clays... and a lot more fun.
