I second the "not much fun" quote from the previous post. I would also ask that since you have a gun that isn't the easiest to find, why would you want to put a steady diet of 357's through it (even if you could deal with the "unfun" recoil). Even though they are made for .357's the 60-10 will surely loosen up much more quickly than a larger K or L framed gun. I'd shoot enough of the ammo you are going to carry to feel comfortable with it, and then shoot it with 38's for practice most of the time.
If you really want to blast away a lot with .357's buy a 686 or GP-100, and if you must use a J size gun, get an SP-101. Stronger and can be found in any gun store.
