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.
 
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?
 
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."

thanks for your reply bob , is it feasible to build a 444 on a P14/M17 , or is the no4 enfield easier to build? i know where i can buy a lothar walther barrel in 44, 1-38 twist , but i think with a barrel crown of .650" the profile is too light .
