Ruger 357 ammo? Need Help

Hello
I have a new Ruger 357 GP100 and have a question on ammo for this gun.
I see at the local Walmart has 357 Sig target bullets are these ok to use in my hand gun?
Below is a picture of the gun. Thanks for your help

In fact a list of except-able ammo would be great.

Please advise
Mark

.357 Sig was developed by necking down the .40 S&W cartridge to .357 diameter. It is a semi-automatic pistol bullet unsuitable for the Ruger (or any other .357/38 special) revolver. Stick with 38 special or .357 magnum ammunition for your revolver. Happy New Year & safe shooting.

No sir, they are not.


357sig is a round based on a 40 caliber (or 10mm) cartridge necked down to 9mm (.355 inches). They will not fit or work in a 357mag.


BTW, your use of the confuses me a bit. It makes me think that your question is in jest. If you are serious and are wishing to "smile" at us then the appropriate emoticon would be this .



Oh my God, emoticon etiquette. Who'd have thunk?

A GP100 is a 357Magnum. It can therefore eat all 357Magnum, 38Special and 38Special "+P" and "+P+" ammo.

The max pressure spec for 38Spl is about 18,000psi. "+P" means extra pressure, generally about 10% over that tops. "+P+" is "God only knows" but at least somewhat less than 357Magnum pressures. (Some of it damned close to 357 levels.)

Max pressure TODAY for 357Mag is 35,000psi per SAAMI. It used to be 43,500. A few ammo houses load their top stuff at the old standard - Buffalo Bore, DoubleTap Ammo, Grizzly Ammo. The GP100 is strong enough to eat that stuff too.

It CANNOT eat 357Sig (won't fit at all), 357Maximum (too long), 38S&W (too fat).

357 Sig Bullets

RagenRat,

Not following your initial question. If you are asing if the Wal-Mart Winchester 357 Sig ammo is usable in your 357 Mag pistol, then the answer is no. If you are asking if the Winchester 38 Special or 357 Mag ammo THAT IS loaded with the the 357 Sig bullet is useable in your 357 Mag pistol, then the answer is yes.

I'm guessing that due to the recent ammo demand, Winchester settled on a common bullet to use in all three loading.

No, 357 Sig is NOT for a .40 caliber pistol of any type

Thanks guys that clears my questions.
It is amazing how fast a mistake can be made by a inexperienced user.

My hats off to you guy's that know all of this stuff, I sure would have hated to damage my gun or myself with the incorrect ammo

You know nobody at Walmart would have straightened me out.
Thank's again to all of you.
Mark

Reading the manual clears this ammo stuff up. It does sound like someone needs to start over. baby steps. .22lr, .38 special, .357 mag...baby steps...

Don't try to shoot undersized .357 sig ammo in a .40 S&W caliber gun. You need to get a custom barrel for that caliber.

Ammo for Ruger GP 100

You've spent about a grand on two hanguns and you don't know what kind of ammo to use. This can't be a serious post or you are a danger to anyone around you.

Being the question has been answered this should have been the first clue.

Question- Did the Ruger come with a owners manual? If it did shame on you for NOT reading it. Did you bother to ask the ammo question where you purchased the gun?

RagenRat,

First of all, Welcome to The Firing Line!

Everyone has to start somewhere and you've come to a good place.

As has been said, the manual which came with the handgun will tell you what ammunition is appropriate to use. Ammunition names can be confusing and it isn't unheard of for someone to buy .38S&W only to find out later that it won't work in their .38 special. You did the right thing by asking.

You didn't ask about using it in your .40S&W until someone told you the .357sig is a necked down 40 caliber. That shows you're thinking. You haven't seen what a .357sig cartridge looks like and you may not know what "necked down" means. It means the case mouth opening was reduced to accept a smaller bullet. In this case a 9mm (.355") bullet. The ".357" is strictly for name recognition and to make it sound like the venerable .357mag. It causes confusion and in this case brought you here.

Had you bought the .357sig and tried them in your .40S&W they may have worked. The accuracy would have been abysmal with the bullet being so much under bore size, but most likely would not have damaged anything but your pride.

Read the manuals and get the proper ammunition for your handguns. If you didn't get a manual; they are usually available for free either on line or by contacting the maker.

Welcome again to the club.

This.

Read your owners manual at least.

P.S. I hope for your sake that you do not actually have handguns IN Chicago.

Well not for the next six months at least (the subject is due before the US Supreme Court this year!).

He could easily be just outside though. Let's not judge too quickly here...

If the GP100 did not come with a manual, or you have lost it, Ruger will provide you one for free. You can either download one on their website or request one.

I suggest looking up an NRA basic pistol class in your area:

Be careful if your going to mail order ammo too. It's esy to order the Sig's if your not paying attention. I got some Magsafes that way, thank God it was only 8 rounds at $15.

I still have them.
