Want To Buy Used .460 or .378 Weatherby Brass

[Remington Roller]

I have a vintage Remington rolling block musket that was rechambered by G Kynoch about a century ago. It has a mint bore and I want to use it for long range black powder matches. I can make brass from .460 or .378 Weatherby cases and need about 100 count. This will only be an occasional use rifle so cost is a factor. I am in New Zealand for any possible shipping considerations/limitations but have a US shipping address if that helps.
Some case mouth damage is acceptable as they will need to be shortened.
If anyone can help would be greatly appreciated. Please PM.
Thanks
Steve

Got a Leica 2.4-16x56mm Magnus that I’ve been waiting to put on something, should be a good set up
