My Father-in-law gave me a project rifle this weekend, it is a Continsouza model Mle-M-16 made in 1917. From what I was told it is an 8mm x 50R cartridge. Does anyone know anything about the rifle or cartridge? Before I invest in refinishing, a reloading press and dies, scope, and all I am hoping for some background. Thanks in advance for any and all information!
