I have a weird question about how much a muzzle brake reduces felt recoil of a rifle. I'm still a newer shooter so I have some noobie questions so bear with me here.
Due to an unfortunate event, I broke my humerus (bone in your upper arm by your bicep and tricep) on my dominant side; the side I shoulder the rifle on. I own a rem 700 sps (non tactical version so no heavy barrel) in 7mm rem mag and would still like to make a couple trips out this year before winter comes. I can shoot a .223 with zero problems or pain but don't have anything bigger to shoot so I can't speak for anything larger than that yet, but I know my arm wont hold up to the recoil of the 7mm rem mag the way it is in its current configuration. Basically my question is how much does a muzzle brake reduce recoil? Can I equip a muzzle brake to my current rifle barrel even tho it is unthreaded and the non heavy version? Can anyone recommend a brake or smith I can ship my rifle to? I want to reduce recoil as much as possible and don't care about how loud it makes the rifle. I also almost always shoot from prone so I want a brake that wont kick dirt in my face. I live close to Saskatoon, Sk so a gunsmith in that area would be preferred so I don't have to ship my rifle away if possible.
I know there are other ways to reduce recoil but I would like to specifically focus on muzzle brakes for now.

Thought I might as well include a pic of my arm so you know what I'm dealing with haha. Its been roughly a month and a half since surgery so this pic is a bit old.
Thanks in advance.
