Not to argue but, I promise you if you shot my 300 Rum 4 times in a row without a brake , your shoulder would be badly bruised! No matter technique you use!
Millions of people have Brakes installed, its not a macho thing on how much a guy can take! Its about being comfortable shooting a rifle! Kinda like a pad on a wooden chair. It just makes it better..
I'm not against brakes, I have them on 2 handguns (300 Rum and 338/375 Ruger) and one rifle (375 Rum improved). These are dedicated long range guns though, so seeing hits is important.
And I had a 300 RUM rifle for about a year. I shot it quite frequently and would never have braked it. Sold it when I got the 300 Rum pistol.

Agree Yorkie. The brake comes of during hunting season. My go to hunter is a lightweight 300 ultra, and not being recoil sensitive, have never shot it with a brake. No problem putting 20 or more in a session. Brakes go back on when pinging long range targets so as to spot the hits!
