Any current sources for some of the harder to find ammo? 600/700NE, 4 bore, 950 jdj?

I’m an avid gun collector and want to expand my collection into some of the more odd / rare rounds. Wondering if anyone had any good suggestions on places to start tracking some down

There is a fellow on youtube (Kentucky Ballistics) who I believe shoots all of those. Don't know if he actually owns all the rifles, though. But perhaps he would be willing to part with some brass if/when they have been reloaded enough times.

Not sure what country you are in but if you were to find a few collectors or actually join a Cartridge Collecting Club you would find a amazing amount of old & new cartridges, I only a week or two back added another 4 Bore rifle round & .577 Eley/Boxer revolver cartridge to my small collection.

Then last weekend found a single barrel 8ga shotgun, today I heard of a 4 bore muzzle loader to look at !

That's a 4 Bore .500 Eley .357Mag .577 Eley
