I'll be the nay-sayer.
I can't stand snub-guns in .357.
Recoil and muzzle blast is ungodly.
.38 Special is as much as I'll allow in a snub.
Further, if you shoot "mostly .38's" in the .357, you are probably also going to shoot the crummy "range ammo" with the soft lead bullets and sticky wax lube. Yes, with enough determination, you can scrub-out the residue left in the cylinders by that junky ammo. But, if you don't, and you shoot .357's, better have your rod and mallet handy when you want to eject the spent .357 cases.
If you completely stick to .38's in the .357, you end up with a gun that was supposed to be a lightweight that weighs more than it should with just dead weight in the cylinder.
W.E.G.
I'll agree with you that a .357 in a 2" barrel has excessive blast and noise (especially if fired indoors). But I take serious issue with the rest of your post.
I have had a S&W Model 19 .357 since 1971. I have fired many, many rounds through it, 90% of them 38's. And yes, most of them reloads with cast bullets over Unique or Bullseye powder. I have never had a problem with extracting fired 357's that required more than a little more pressure on the extractor rod. Rod and mallet not Required!
Oh, by the way, the gun weighs exactly the same 38 oz it did the day I bought it!
Jermz - Don't be afraid to shoot that gun often. While it is true that 38 Scpl loads will leave a ring of burnt powder, a good cleaning of the cylinder bores with a brass brush and solvent, followed by a pass with the bore snake will keep your cylinder clear. It won't require breaking your arm over.
Do practice a lot, a snub requires a little getting used to due to the short barrel. Once your proficiency reaches a comfortable level, shoot some 357's to get used to the difference.
My Model 19 is my house gun, but I don't have it loaded with 357's. It stands ready with 38 Spcl +P hollowpoints to avoid overpenetration. You may want to consider the same.
My carry gun is a Taurus M85 SS 3"inch, with Crimson Trace grips, loaded with the same +P and I love it.
