Ruger Convertible Black Hawk Question

[Lefty Red]

Will they shot 380ACP in the 9mm cyclinder?

Just wondering.......

[contender1]

No. The headspacing is off the mouth,, and the 380 will slide into the cylinder.

I was thinking as much. Thanks!

.380 ACP is much smaller in diameter than the 9mm, not even close.

You CAN use .380 Rimmed Short (9x17R) in the Ruger 9mm cylinder, but cases swell a bit.

OK with light Cowboy loads, I use .38 Short Colt data.

Wow, never saw that caliber before!

I will stick with 9s, as they are plentiful.

Thank you gentlemen.

Grafs had these on close out a year ago, they had ordered a bunch in error thinking they were .380 ACP, but turned out that they weren't. They closed them out really cheap, so I bought 2000!

I use them in my Webley & Scott .380 Rimmed, a Ruger India Model, Colt .38 New Police and 9mm cylinder of my Ruger convertible Blackhawk. One size fits all plinker with 2.5 grains of Bullseye and Accurate 36-155D for 720 fps.

Wouldthey work in a 38/357? Or too small?

If brass hasn't been previously fire-formed in a larger diameter 9mm or .38 S&W chamber they will work like .38 Short Colts in a .38 or .357. Unfired body diameter is .373 cylindrical, case length .687, rim diameter .425, rim thickness .050, which is a bit thin, but works OK.
