A friend of mine picked up a combination gun in this caliber and want's me to help him build /buy some ammo for it . I have worked with several British nitro cartridges but never this one.
Any advice about where to start with this one.

just a W A G but you might make useable brass from 348 winchester??
You need to do a chamber cast to get the dimensions that you will need. Do you have any of the cartridge conversion books? They can sometimes give you a hint of how to proceed. Check CH4D.com to see if he might already have that in his catalog.

There is no 'right' that requires me to work for you or you to work for me!
That's the same case as the brit 450/400 bpe or nitro express I believe. Still used as a hunting round in Switzerland.
thank you for the replies. I have some leads now . I have some Bertram 450/400 2 3/8 cases in route. I was surprised that quick load has the 10.3 x 60 R listed. dies and bullets are next. Bore is supposed to be .415. I suppose .416 cast would work. I'll see how this works.
A case full of black, slightly compressed. 400 slick with two wraps of 16lb paper, you'll be very close.
Works for me.
