What Firearms or rounds interchange as in Allow Multi Calibers ?
Not with standing the 38sp in a 357 or .223/5.56

Was wondering what other firearms or calibers are interchanged, friend an I were discussing it and thought would be a good topic of discussion.

45lc IN a 454 casull

 

[Superglide]

.327 (my favorite) shoots .32 H&R, 32 S&W long, 32 S&W, and in my single action 32ACP
Mild to Wild!

 

[3MTA3]

44, 44 special, and 44 magnum in a 44 magnum.

 

[DuneHopper]

Gees I am glad I asked, really never paid much attention and you guys know your stuff, nice information.

 

[3MTA3]

Forgot to mention that you can fire 40 S&W in a 10MM pistol.

 

[Superglide]

And of course Ruger makes it's convertible models to shoot 9mm in a 357 gun, 45ACP & 45 Colt or even one to switch between 10mm and 40 S&W.

 

[Kruel J]

.380 in a 9mm. Hand racking the slide notwithstanding.

 

[3MTA3]

The Taurus Judge fires 45 Colt and 410 shotshells. Don't think I's try the 545 Casull in it.

 

[v0lcom13sn0w]

i have a rifle that'll shoot 22lr 22 long and 22 short

 

[No_Regerts]

9mm Parabellum, 9x19, and 9mm Luger.

 

[American123]

.22 Lr from an 5.56/.223 AR when equipped the the propper BCG and magazine

+1, I've done it several times in my G20.

 

[Superglide]

I probably should have pointed out that a 32 H&R mag will also shoot the 32 S&W rounds. Another good caliber, the H&R can be loaded to what could be called a pretty zippy load.
I like shooting the S&W long because they:
a) cost a lot less
b) have 22-like recoil
c) are reloadable (unlike 22)

i have a rifle that'll shoot 22lr 22 long and 22 short

And they said it couldn't be done

 

[v0lcom13sn0w]

And they said it couldn't be done

it says it right on the barrel lol

 

[HB of CJ]

Yep. Full house hot 9mm in specific handguns plus the SMGs. Yep, hot 44mags in specific revolvers and lever action rifles. Have we mentioned .22rf both in all the handguns and rifles?

30 Carbine maybe in some revolvers, (huge flash and blast) and the 30 USGI Carbine.

 

[CountryGent]

A revolver in .460 S&W Magnum can also run .45 Schofield, .45 Long Colt and .454 Casull.

 

[Ura-Ki]

.45 COLT in some .45/70 and some .45/90 can take both shorter cartridges+ some can also take .410 shot shells and with moon clips, .45ACP! I have a .45/90 sharps replica that can take all above! Even better, with a barrel insert can shoot some smaller cartridges just fine!

 

[coop44]

Any rifle round that is fire formed into another. Most weatherby rounds and Wildcats fall into this category.
