Re: AM Painkiller brakes?
You don't necessarily need a big PK brake for your 7WSM. I have a CSR (Center Shot Rifles) brake on my 7SAUM and the recoil is very minimal. I can start to see my impacts at around 300 yds or so. My barrel is .8" at the muzzle and the brake is 1" in dia and it looks very good and smooth.
It would be interesting to see if a bigger brake would give you more recoil reduction or just give you a little more weight to carry. Once I build a bigger rifle (something in the .338) I'll put on a 4 port Muscle Brake.
