If you are speaking of the Buckeye Specials,, yes. If you are discussing the new 40 S&W/.10mm,, yes.
I have shot both & enjoy both.

Yes, and the .38-40 is an extremely easy cartridge to shoot in a revolver.

In all three chamberings, they are delightful.

But unless you're handloading the .38-40, or the nostalgia factor is more important, the .40 and/or 10mm is more convenient, cheaper, and will do everything the .38-40 will do.

I've shot .38-40's, and I own a .40/10mm convertible. The convenience of the 10mm would cause the .38-40 cylinder to remain in the safe.

YMMV. :mrgreen:

I am considering getting the 10mm/.40 convertible and having David Clements rechamber the .40 cylinder to a tight .38-40. A true 10mm magnum. Reeder's .401 GNR would be a viable alternative also

You'll have a gun that'll shoot the true .40 WCF Magnum:

Unlike you, I am a big fan of the 10MM / 38'40. Have this matched pair I looked for, for some time. :) Walked into a small shop in the valley and there they were. Home they came. :mrgreen: Later acquired the proper holsters for the pair. Natrual for the 10MM-38/40 and black for the 32/20-32MAG. These are older photos, but the stocks are now Ivory on both. Always wished I could find a old Winchester in 38/40 I could afford. :) Read once there was a engineer up North that kept one in the cab of his train to dispatch moose on the tracks. I load for and shoot both of these. :)

J.R. WEEMS,
Beautiful pair of revolvers. I too have Buckeye Holsters for mine, both tan. Your black one is a beauty! I'll have to keep my eyes open for one.
Best

Hawkeye- the black one came that way and shows no sign of being 'home dyed' which lead me to believe it was factory. Did yours come with the guns?? :)

No I bought them seperate. I knew that there were black ones (very scarce) made, but not Buckeye specific. great score.

I consider the Buckeye convertibles (and the JSS 44M/44-40) some of the finest work Ruger has done with the SA guns.

OP: I shoot both 10mm and 38-40 with regularity. The 10mm has put meat in the freezer!

CAS-- nice looking gun!! Have never been able to find softer lead for the 38/40, but it doesnt matter. What bullet are those?? I have used Hornady XTP's for all my hunting loads for years. :)

I have a Winchester 1892 with an awful bore that only shoots well with soft lead. I used to buy bullets from a company offering a soft "cowboy alloy" , but they've since gone out of business.


The bullets in the photo are 180 XTP's with a cannelure added. Pushing them closer to 1500 than 1400fps. ;)

I have the following convertibles already
32-20 and 32 H&R
9mm and 357 Mag
45ACp and 45 LC.
I have a 38-40 in a Colt and a 44-40 in a Colt.
I'm kind of Ruger crazy and just like the convertibles.

I don't know how easy it will be to find one this far North but I do have a couple shops that I am going to put the bug in their ear and see what it is going to cost me..

Thanks Ken.

Apologies if I'm hijacking this thread, but I have some questions.

Would it be accurate to say that the .38-40 is a necked-down .44-40? And where does ".38" come in to the equation? The projectile is .401", is it not?

Sorry for the randomness...

In the case of the .38-40, the "38" refers to the black powder charge while the "40" refers to the (approximate) bore size.

Yes, this is just the opposite of the .44-40 designation, where the "44" is the (approximate) bore size and the "40" is the powder charge.

Anything to add confusion.

:roll: :lol: :roll:

They are .38 Winchester Centerfire and .44 Winchester Centetfire and they are rifle rounds. ;)

The gun is a "must have, must shoot" for any serious Ruger enthusiast.
Makes a fine tree stand revolver for making venison. 1100+fps 200gr XTPs in 10mm. I know this much...
