I agree. Shoot them until the cows come home. I agree with the earlier remarks.

Even the 125 grain loads at 1400 fps are not dangerous at all. They seem sto accelerate wear, but they are not dangerous, by any means.

I have never seen anything official by S&W, but have read many horror stories of forcing cone damage or flame cutting with the 357 load that was 125 grain JHP at 1400. I have never heard of the "problem" (if there is one) with any other load. Again, even this load is not dangerous, it just accelerates wear.

Feel free to use them occasionally, and do most practice with 38s and you will be fine.

While spreading rumors, I have "heard" that the so-called Treaury load (38 special 110 grain JHP at high velocity) shook the dickens out of the Model 10s and K frames requiring earlier than normal correction for timing and end shake, etc., but I have never heard that the load was dangerous to the gun.
