.40 caliber through a .357 Magnum

[NeilLedger1981]

New to this revolver, went to get .357 rounds and I was told I can pass .38
Specials through this revolver which are cheaper! Ok thanks gun guy. He then tells me I can also put .40 cal through it. Is this true? I’ve heard of the .38 specials but not .40 cal? TIA

 

[groundskeeper willy]

No its not possible.

 

[mikeyb]

Definitely not. .38 Specials in a. 357 Magnum is normal, though.

 

[calibrecarstairs]

.357 is a rimmed cartridge.

.40 is a rimless cartridge.

Problem...

 

[All in fun]

Whoever gun guy is, he may not like you...just sayin'

Hahahahaha

Have the seller demonstrate the idea before you hand over some money......

357 is closer to a 9mm and 9mm would work if you have a proper cylinder

 

[NeilLedger1981]

I have 45 and a 9mm pistols.

Did I just buy ammo off this idiot I can’t shoot?

Yep

I would question who the idiot is here. You own handguns and don't know what the proper ammo is for them?

 

[marshall]

Yep, what the hell are you talking about.
Did you buy a 357 mag revolver?, I hope not from the idiot that says you can use 40 cal.
You can , and I do shoot 38 special ammo out of a 357 mag. gun. the only difference is the length of the case.
You can't put a 357m in a 38 special , or a 38 s&w gun because of the length.
a 38 cal is 9mm in size, but the cases are different.
Post what make and model of gun you are talking about and we can give you advice.
38 is easy shooting, 357 mag is not great for a new shooter, plus way more money. sort of like your 9mm and 45 pistols, you have ,I guess.

Wait. You own at least two pistols, and yet bought 40 (s&w I assume?) to shoot through a 357 mag revolver?

I assume you have realized that you can't fit 9mm in a 45acp....?

 

[Milspectacles]

The only instance of .40 being able to fire through a .38 is a .38-40 (actually .401) with a .40 S&W cylinder, Ruger used to make a convertible model

But it sounds like this guy really pulled your chain

 

[VanMan]

Can you confirm please which model of revolver you have? A S&W 586/686 or 27/28 are chambered in 357mag and you can fire 38sp from them. A S&W 610 is chambered in 10mm and you can fire 40S&W through it as it uses moon clips to headspace the 10mm and 40S&W rounds.

 

[coldestcanuck]

.38 and .357 are the same bore measured in 2 different ways. 9mm bullets are usually a couple of thou smaller.

 

[Leg]

Ummmm.... isn’t firearms safety training still mandatory?

 

[Boomer686]

Coming soon: ".357 for sale: excellent condition / barely used... only seen one round of .40"

Honestly though did you not learn anything in your PAL/RPal courses?

 

[redshooter]

There's an obvious answer to this 38/357 is a 0.357" projectile, 40/10mm is 0.400"...

OP must be having a joke with us, nobody that clueless could pass the restricted test.
