I am happy to own a S&W 686 4"

I am not exactly an expert when it comes to specifics of ammo means, as far as the bullet weight, grains etc...

What I am looking for is a good, somewhat cheap, all around plinking ammo. I am looking for .38 as well as .357, as I would like to get used to both.

Also, any info on using jacketed, non jacketed, etc.

Anyways, thanks everyone.
