I have a 404 Express made by Barnes before he connected with Johnson. Late 40's early 50's? The rifle is a .416 caliber...don't ask me why 404 Express. It predates the Chatfield Taylor. The only difference between this chambering and the Chatfield-Taylor, is the Taylor has a slightly smaller shoulder diameter. I mean slight perhaps .010.

The interest in this cartridge configuration goes way back....I think at one time the Taylor was being looked at to become a commercial loading....some else might be able to shed some light on that.

I have only used it on deer using Barnes 300 grain bullet. It is extremely accurate and pleasant to shoot.

It is built on a 98 Mauser.
