I would look very carefully at the cylinder and inspect for damage if it has been fired with full house .357 magnum loads. My personal opinion is to stick with .38 Special powder charges if you use .357 cases for reloading.
I am not a gunsmith but would suggest that you be cautious.

BTW.....I moved to AZ a little over a year ago after living in the Seattle area for 30 years.
