For those who may have followed a prior thread on the development of a 404 (.423") wildcat based on the 375 Ruger case, this is an update.
http://www.24hourcampfire.com/ubbthreads/ubbthreads.php/ubb/showflat/Number/2464797/page/0/fpart/1 The donor rifle, a Ruger Hawkeye African in 375 Ruger has now been re-bored to .423" and test fired by the GS (Danny Pedersen) successfully today. I should have the rifle back within 2 weeks and ready for load development over the spring. As far as I can tell this is the first firing of this new wildcat cartridge. Will post further updates with load data and range tests as the project proceeds. Thanks again to muledeer (the Alaskan variety) and to Ray for the collaboration on this 24HCF development.
