I magna ported a pre 64 Model 70 in 300 Weatherby (formerly 300 H&H, I didn't do it). I have been completely satisfied with it. I agree with the posters about the amount of recoil reduction occurred. However, what I like most is the reduction in muzzle jump and twist. Seems to send recoil more straight back. I would do it again given the choice. I refuse to be around anyone shooting a muzzle brake.
