Good info. I thought the Brit's 7mm was still born and maybe a case or 2 existed in some museum somewhere. Actual photos exist and mere mortals can touch real cartridges. Wow!

It is funny that such a large action was thought to be necessary,  maybe they were thinking that an upgrade to a longer cartridge could have been in the future. Even the Ross does not look so big that it would not have fit in normal action.

Myself I have never seen a need for magnum cartridges. The pig in the photo was hit with a 150 grain varmit/target boat tail hollow point in the shoulder and was dead before he hit the ground. Estimated weight 500 to 600 lbs. This guy had a fair amount of domestic pig in him most black wild pigs here top out at somewhere around 350lbs.
