Long range AND steel...hmm. If by steel you mean paper then you you have a few choices but there's only one standing offer that i know of but it costs a bit to go on that farm.
The NRA clubs in the Clevedon area (there are 2) would be the go IMO. Check in the clubs section for Akarana if you're keen to shoot 400, 500 and 600y on May 7th (the next shoot).
I do have a contact up north but im a lazy arse who hasnt replaced a certain smashed up gong (thats evidently made out of butter).
