Trade 100 rounds new Belmont 308 150gr SP for any 45/70 ammo, bullets, cases etc

I've bought a 45/70 and getting into reloading, so have 100 rds of Belmont 308 I don't need.
Has anyone got any 45/70 stuff they want to trade (or sell)?
I'd take cases, loaded rounds, projectiles, suitable powders, dies or other reloading gear for 45/70
I'm in Auckland but drive to Taranaki often so can meet up anywhere in between

I've got 50 new pieces of Starline. $55 posted.

Also have 9 loaded rounds but probably not worth the hassle of doing a form.
