Carl Steigle double rifle

[6pt-Sika]

Very interesting !

I've got a Kettner drilling that's rifle barrel is 10.75x65R Collath . That cartridge is easily made from the 405 WIN case .

Here is a bit of info. This is from Ken Howell's Designing and Forming Custom Cartridges. No load data at the moment, but I'll dig around.
