Thanks for all of your input.

I'm not going to jeopardize my well being for a couple of bucks.

If ammo were in short supply and I were being overrun by zombies, I wouldn't hesitate using 38 super in my 686.

However, since there isn't a zombie in site, and I have several cases of 38 special and 357 at my disposal, the 38 super will be sold.

Now, to figure out how to post pictures...

Again, thank you all for sharing your knowledge and experience.
