357, 357 mag and 38

#1

Post by mloamiller » Wed Oct 17, 2018 8:43 am

My understanding is that any .357 magnum revolver can also shoot .38 rounds; is that accurate?

Is there a difference between a .357 and .357 magnum revolver, or are those the same thing?
If there is a difference, can a .357 revolver (not a magnum) also shoot .38s?

I've not seen a plain .357 designation, outside the Mag or Sig, and obviously the Sig is an entirely different animal. (other than people just talking about .357 Mag and not saying Mag) And if you are a history buff, there was the .38 S&W, which obviously is different than a .38 Special.

.38 special vs .357 Mag
The case length is different from 38 to 357mag- according to the specs by about .135". And pressure max is about double in 357mag. According to the Lyman 4th Cast Bullet (just what I had out on the desk) there is also a difference in rim thickness by .002, with 357mag being thicker.

Yes .357 mag guns can shoot 38 special, but not the other way around. Just be careful to clean the cylinders well or the .357 mags brass will stick badly if there is a build up of gunk in them. Ask me how I know! :lol:

.38 Special, yes, upon which the .357 Mag was based - there are a bunch of .38 cartridges (.38 S&W, .38 Short Colt, .38 Long Colt, etc) out there, so being specific is important.

When applied to a .357 Magnum revolver, it's the same cartridge - outside of that, you get .357 Mag semi-autos (Desert Eagle, Coonan, etc) and other .357 cartridges (.357 Sig, .357 Maximum, etc)

Most likely it’s the same but there’s no hard and fast rule. There were 357 maximum revolvers made but I’d expect them to be marked as such.

Sure - .357 Maximum would be one example (the cylinder is substantially longer), but generally-speaking most folks who talk about a .357 revolver would typically be referring to a .357 Magnum.

I'm curious about the reason, given your posted qualifications, for these odd questions - what's going on?

As stated above there are 357 maximum revolvers (which are lengthened 357 magnum cases cable of more velocity). For a brief time you could find revolvers in 357 supermag, but they were identical to the 357 maximum when that cartridge was commercially released in the early 1980's (1983 or 84?). Then there is the 353 Casull, which pushes the boundaries of the 357 to the max. The 353 uses the same brass & bullets, but the Freedom Arms revolvers wrings every ounce of velocity out of the cartridge... and the brass is extremely short lived.

Bottom line, you have a revolver in 357, chances are its a 357 magnum and should be stamped as 357 magnum, or 357 remington magnum.

357 magnum vs 357 maximum (or as some call it, the supermag) There are actually a couple on GB if you look.

I’ve never heard of 353 Casull but I’m intrigued by it and it would go well with my FA 83 in 454 Casull.
