Doesn't the new 28 Nosler have quite a bit more powder capacity than the Mashpotato ? Isn't the Mashburn just a 300 WM case ?
It does.
I just checked the Nosler site.
28 Nosler with 175 gr. bullet, 90 gr. H20 case capacity
300 WM with 175/180 gr. bullet, 82.3 gr. "
300 Wby with the same bullet 91.8 gr. "
I remembered that the 6.5/300 Wby was pretty close to the 26 Nos, although the new Wby round is hotter. Slightly more case capacity plus Roy's magic freebore...
Using the .300 WM as a basis, the 28 Nos is a bigger round than the 7mm Mizzum.
Bob may be able to educate us on the exact case capacity of the Mashburn with 175 gr. bullet.
