You may wish to get the Oct. 15 issue of, "Gun Week", where there is a two-page article discussing the .357 ammo issue, and how to select the best .357 gun for your own needs.

It is not in the Online edition, but I'll link that here, as it has contact info. Click the button, "Current Issue", then scroll down on that page until you see the address and phone number of the publication. I think current issues are $2.00, but ask.

The writer has studied the matter for some 30 years, and talked with S&W officials and engineers at the major ammo makers. Also, a number of gunsmiths. There is considerable information there, and it not anecdotal stuff from gun forums.
