Hi Guys I have a couple of cartridges that I am not aware of

The first has a head stamp of 4005 Kynoch it is a very large rifle round, any idea of the age or calibre? what they may be worth?

The second has a head stamp of 350 Magnum Rigby nitro, I assume its a 350 magnum but for what rifle and what would these be worth? what is it's age?

Thanks for your help

"...4005 Kynoch..." Well, Kynoch is an old Brit ammo company. There is a .405 Winchester loaded by them, but no 4005. Kynoch loaded .405 Win is worth about $8 each. Usually headstamped 'Kynoch .405 W' Does it look like this? http://www.reloadersnest.com/frontpage.asp?CaliberID=84
"...its a 350 magnum..." Yes, but if it looks like this, it's not the .350 Remington Mag. It's an old Brit hunting cartridge too. Usually headstamped 'RIGBY .350 MAGNUM NITRO'. Worth about $3 each.
