Hello, Trebla. I don't know. I cannot speak to "Anonymous's" experiences and opinions as expressed on Mr. Hawks' site. The article does appear somewhat dated as Nyclads are no longer available to the general public and S&W does now rate its J-frames for +P. I can only speak for my own revolvers, but they've certainly had more than that. In the older Airweights which are not rated for +P, I have limited the amount to enough perhaps 50 rnds per year.
Both of these are Airweights. The 642 at the top of the picture is not rated for +P and is the traditional J-frame. On its barrel is stamped "38 Special CTG". The newer 642 shown below is on the slightly "stretched" frame that was adopted when S&W began offering J-frames in .357 magnum. It's barrel is stamped "38 S&W SPL +P"
As is the case with 9mm, there is +P and there is +P. I still have some of the old .38 Special Corbon 115-gr. +P+, which I'm told is actually +P. I don't know, but I do know that it's "hot".
I am a bit hesitant to shoot this in less than a steel frame J and prefer the K-frame or a Ruger SP101. The velocity shown on the chronograph readout is from the 1 7/8" bbl of the 642 pictured. I have concerns about the thin forcing cone with this round. I figure that if the full-bore .357 magnum 125-gr. JHP can hurt the thicker K-frame, then a fast 115-gr. JHP might do the same with the thinner J-frame.
There is no doubt in my mind that the +P loads will wear out a J-frame quicker than standard pressure. I don't know if it will do this to a particular revolver by cracking the frame, splitting the forcing cone, or just gradually stretching the frame.
I agree that most practice can be done with standard pressure loads, but will still carry +P 158-gr. LSWCHP +P for serious purposes. I just cannot forget visiting with a young man who had been shot, but was sitting on a curb and holding his head in his hands. I called an ambulance while trying to find out who shot him. He looked sick but was helped to the ambulance where he died 4 mins later enroute to the hospital. He had been shot through the heart with the standard pressure 148-gr. wadcutter.
I have little doubt that the steel J-frames will take a pounding longer than the Airweights, but I'm not sure I'm convinced that 100 shots of +P will trash one of the latter.
Just because I have not seen it doesn't mean that it hasn't happened, so I would suggest going with what
you feel is prudent. For me, that remains the Remington load mentioned before.
Best.
