Wow. That just goes to show recoil is a personal thing. That rifle calculates as having ~38+ ft-lbs if the all up weight is 11 lbs with scope. I've shot a .338 Lapua with a Holland bake - it feels about like my .30-06 (a 1953 M70 with blued steel butt plate). I can't imagine shooting that Lapua with out a brake. My ears already ring continuously - even with muffs on the brake is too much noise - I'd need muffs plus foam ear plugs and that would suck in the field.
I've found that around 25 ft-lbs (calculated) is my limit so I'm planning to build my .338 Win Mag to be 12.5 lbs all up with scope. I'd have to have a brake on a .338 RUM or have it weigh at least 17 lbs (more than this 68 year old 5'-7" 170 pound guy wants to carry around). That said, the .338 RUM sure looks like one fantastic cartridge. I wish there was such a thing as a quiet brake but there isn't, at least so far.
