Thinking Of Building A 470

[jwp475]

Based on the 338 Lapua case with the case taper reduced and a 30 or 35 degree shoulder with a .500 case neck length. Or maybe a 470 Mbogo




Plan on using a CZ 550 in 416 Rigby that I have.

I read an article on the 470 Mbogo one time. Sounds like a very interesting project. The 450 Rigby may be more practical, but practical is seldom fun.

470 500 grain TSX, 350 Grain TSX and 270 grain 375

The Mbogo looks fun.

I always thought about the 470 Capstick. Is there a 470 based on the 505?

The 408 Cheytec is based on the 505.
A 470 based on the 505 would be out of this world

From Sir Ron
"
470 Mbogo.
Same case capacity as a 470 Nitro Express.
Use 470 NE load data for plinking loads,
or use the 470 Mbogo to test loads for 470 NE, saving wear and tear on the double rifle.

The 470 Mbogo at same pressure as the 460 Wby can make a 500-grainer go faster.
That 500-gr TSX for the .475-calibers can be sped along at 2700 to 2800 fps from a 470 Mbogo
versus the 460 Wby 500-grainer at 2600 to 2700 fps.
That .475-cal./500-grain TSX is a pretty bullet, much better proportioned than a .458-cal./500-grainer.
2500 fps is the happy MV with that bullet in a 470 Mbogo."

There's the 470 A&M I think. The story is recoil was vicious.
