Sorry, don't know postcoad but the Sat Nav co-ordinates are
Get off the M5 southbound at Junction 28 (Cullumpton) and turn left towards HONITON.
Follow that road for about 3-4 miles and there is a white pub on the Right called "The Cottage Keeper".
Turn right just after the pub (on a sharp bend) and follow the road into the wood. Go straight over at the minor crossroad and the shooting ground is a few hundred yards down on the left, just past the scrapp metal merchants.
I'm sure that Chris will have some signs out from the pub onwards.
