The 450/400 3" N.E. is a great cartridge, but I'd rather get the 470NE if you are looking at the 450NE.
Better resale and better ammo availability.
A mate's Heym 470NE is regulated for Federal ammo and my Merkel 470NE for Norma,
Its easy enough to duplicate the loads with a crony and given that supply of factory ammo in NZ has been scarce/limited for these types of calibres I'd recommend handloading for it.
and get a copy of G. Wright's book - Shooting the British Double Rifle - it has some great info on shooting doubles including load data.
here is my Merkel - Merkel 470 - YouTube
and another with both of them - Duelling 470NE - Heym vs Merkel - YouTube
Once you get a double you wont look back!
