Just as a question for Ruger 357 Maximum revolver owners that actually shoot their guns. Has any one had the top strap actually eroded to the point of significance? I have read that the erosion was the result of using 125 gr ammo in an attempt to get really high velocities. I know that S&W used blast shields on their scandium revolvers and I have an old hand ejector with a bit of erosion on the inside of the top strap so I am not denying the fact that it can happen. Maybe if Ruger had advised the use of 160+ gr ammo, we might still have a great revolver cartridge in a useable frame size.
