475 B & M

Like the 50 B&M and the rest of the B&M family, the 475 B&M is designed for Winchester M70 WSM control feed actions. Same basic 2.240 inch RUM case, just squeezed to .474 caliber. Currently all 475 B&Ms have been built with 18 inch barrels. Bullets from Cutting Edge and North Fork have been designed specifically for the 475 B&M. And as you can see from the trip to Australia below, the bullets have been an enormous success.


The 475 B&M will be the last of the B&M Series based on a 2.240 inch RUM Case, and works from Winchester M70 WSM Rifles, which now consists of the following;


50 B&M

475 B&M

458 B&M

416 B&M

375 B&M

9.3 B&M

475 B&M Goes to Australia

All the basic 475 B&M load data is completed now. Since Gun #1 now has a proud new owner, this left me short of a 475 B&M. I used one of the hi grade bastogne blanks for a new stainless 475 B&M to do all the load data and pressure data. We are happy with Accurate Innovations and this new stock!
