View Full Version : Ruger GP100- Shooting hot or double load .38spcl?

Basically wondering if any harm would be done to a GP100 chambered for 357mag if it fired a hot or double loaded 38spcl. round.

In other words, would it be fairly safe to shoot reloaded(from someone else) 38spcl rounds through a 357 mag (gp 100 no-less) since the gun is already designed to handle a hot load?
Thanks!

Seriously?

Seriously?

I guess I should be serious. There are no specs for a double loaded .38, which is WAY more than the potential energy in a .357 magnum. If you have questionable reloads, no one will advise you that they are ok to shoot.

To help you understand why this is bad, double the powder is more than double the pressure. It would be WAY over the pressure limit for even 357.

I wouldn't. Get one of these and reuse the brass & boolits. Shooting dubious reloads, especially somebody elses, is just asking for trouble.

I've loaded over max rounds and shot them through my GP100 and the rifle primer that I used were slightly cratered. I carried those while hiking/hunting around San Bernardino Mt. rec area intended for mountain lions and 2 legged vermins. Why go to the trouble when I can pack my 10mms.

Not sure if you are serious, but I suggest using a good .357 load and being OK with that.

Dont do it 357 is plenty enough.

This is a monumentally bad idea. If you fire double powder(not pressure, double pressure is a lot less than double powder) loads at the very least you will damage your gun, if not yourself.

Also anyone who says "mind trying my reloads" knows they suck at reloading and want you to pay the gunsmith/medical bills for their experiments.

I'm curious why this is even being considered. What's wrong with simply having a nice 357 load? As others mentioned.. sounds like a bad idea.

Why not just used .357 magnums? Those badboys are special enough.

I looked at some sample load data for 38 +P and .357 mag on handload.com (I haven't started reloading yet, and do NOT vouch for the load data being presented).

using 6.6gr HS6 powder, a 38+P 158gr load @ 1.455" OAL develops 18,700 CUP pressure.

using 9.5gr HS6 powder, a .357 158gr load @ 1.58" develops 41,900 CUP pressure.

can you imagine what 13.2gr @ 1.455" OAL would do? way more powder, and in less case volume?

Bottom Line, as others have said, if you're worried that some of that reloaded .38spl is double charged... don't shoot it.

No. I don't know of any powder that will be remotely safe with a double charge.

I would advise against double loading .38 special. Your next issue is shooting someone else's reloads. I would also say NEVER shoot reloads that you have not personally reloaded.

If you want to be pulling pieces of the frame and cylinder out of your forehead, go ahead and try it.

I saw a Taurus .357 KB from a double charge .38. Half of the cylinder was gone. Only two complete chambers remained of a six shot cylinder. A piece of the topstrap hit the shooter in the forehead, causing some bleeding. Chunks of metal were found all over the area. Most of which we could not determine what part of the gun they were.

Yes I know it was a Taurus and not a Ruger. If it had been a Ruger maybe three of the six chambers would have remained. Perhaps we could of identified more of the pieces. Perhaps the larger topstrap would have cracked the shooters skull, insead of just making him bleed.

If you do this, can I have the rest of the gun afterwards? I've always wanted a KBed revolver for a display. Given Ruger's reputation it would be an awesome display.:eek:
