I've hatched a plan that is on it's way to fruition (to mix my metaphors). I've had a hankering to hunt in NZ for a long while and got over there this year, fantastic place, loved it. So rather than beg borrow or steal a rifle while there I have refurbished and nearly completed an old project.
Its a Martin Enfield in .35 Whelen Rimmed. Ill have more time to put some details in tomorrow.
The cases are Rt to Lt .243 Win, 35 Whelen R, 6.5 x 55R
