500/450 NE Holland and Holland?

[wildwilderness]

I am becoming aware of the vast amount of information there is about double rifle!

What is the thought on the 500/450 cartridge chambered for Holland and Holland rifles? I gather its a proprietary round? so there were a lot less manufacturers over the years.

Are there different sizes of this round?

Is this still a viable cartridge? Can you buy factory ammo? What about reloading supplies? Brass and Dies available? Can you make brass from a 500?

Please educate me on what I don't know!

It’s one of the nicest cartridges of the NE family . It was a variation by HH. Roosevelt used one on his famous safari .
It is made by Kynoch and some others also . but a reloaded cartridge leaves more choices . It uses 480 grain as standard , but 500 grain data around also .

RIA just sold a really nice one a week or so ago. It's a cool caliber,.,....I thought about bidding but I don't need another project. I did do a little leg work and dies would more than likely be available from that outfit in ohio, bertram still can order the brass,....it could be done.
