As has been mentioned the .44 Mag is loaded hotter then Elmer ever intended to go. Elmer's complaint was with the .44 Spl load that he calls little more then a squib load.

I own a 629-1 and a 29-2. These guns have never fired a magnum load as long as I have owned them. I prefer to keep velocity around 1050/1100 fps for any shooting I do with them. It's easier on the gun and me.
