Lee, its time for you to update us!
We had a vote, the results spoke for themselves. A .257" caliber Single Six should be on the drawing board, at least in your head, so where is the project headed?
I dont think we are in any rush but a little discussion couldnt hurt more than some feelings here and there.
Looking at the 25-20 case I agree with you that we could shorten it and get a bit "more" punch than a Hornet case would provide. I think that too it would be more of "our" design and not a copy of Mr Bowens work. But I wonder if we should fireform the case to have straighter walls and a sharper neck?
I have a Single Six donor cylinder on my bench waiting for your call......

Yo Dawgs! May I assume that you are working to grease the path to have a significant number of these built? A single gunsmith might be able to buy enough 257 barrel stock and mass produce 257 barrels and 257 cylinders to save us a few bucks. Might be good to be looking at the same idea for loading dies and bullet molds..

I dont know about all that Stan. But I am going to have one. If he decides to try BOTH cases, I will have a dual cylinder sixgun!!
Bisley. 6" barrel. Prolly octagon too! Might even have to do it on a OM Ruger Single Six!!!

Just looking for some multiple production price breaks.. Decided on what barrel twist we might be needing? Might be time to stir up a group buy on a bullet mold. I'll be wanting a GC that will work in my 255 Banshee too.. Looks like Magma starts at 32. Does Veral Smith make bullet diameters that small? Need to spin him up on a 416 GC mold soon. I'll ask him about a .257 LFN.

Hang on buddy. We are going to have to be very careful about crimp to nose length. I would like to set this wildcat up for the 60 grain Hornady JSP. It should be quite bad to the bone on the smaller stuff.

Fermin.... in the interest of having 2dogs in one, how about a .25-30/50. A .25 bullet in a .308 sabot in a necked down .44 mag, .45 Colt, .500 Linebaugh, or .500 Maximum case. Dan Wesson style tensioned barrel, replaceable, gap adjustable. Guessing here: start with a 1:9" twist. Blackhawk or BFR frame.
Extra barrels would be 5 and 10-inches, with no barrel at all for going out to dinner. Cartridge without sabot simply would be .30/50, or whichever parent case is used. Therefore, extra barrels would come .257 and .308 groove. And, yes, a straighter wall, with sharper shoulder.
(Many years ago I had a Model 53 .22 Jet, with steel insert sleeves for .22 LR. Very loud little beast, admittedly flat shooting. .357 case with 19th century taper; sticky extraction. That and the very high cycles per second sound wave diminished my interest.)
The .41 magnum might balance the .25, with plenty meat around the chamber
Like a wheelgun
this idea keeps orbiting the sun

I was just looking through a book titled, Wildcat Cartridges and found an article titled, .257 Magnum Revolver. It is a shortened version of the .25 Hornet thought to have been developed around WW-II.
There is a diaghram showing case length at 1.300 in.. Velocity with 67 gr. cast slug shown at 1600fps.
In the authors opinion (Al Miller) the cartridge would make a neat round for a small-game rifle but impractical in a pistol, and is too much in a handgun.

David, You may have missed the original thread on this subject. A vote was taken and the overwhelming choice was a 25 caliber cartridge that would fit in a rechambered Single Six 22 cylinder. Lee Martin is hammering out the details, will do the machine work, and the only decision left is if we are going to shorten the Hornet case or the original 25-20 case.
Richp, I have read that article, but we have come along way since WWII. Nowadays we have sixguns chambered for all sorts of rifle cartridges.

I think the 25-20 case would give you a whole lot more velocity potential with whatever weight bullet you choose to load. Axe has a good point about a group buy on bullet mold and barrels. The only problem is that there is a really wide range of bullet weights in 25 cal. I know from experience that in a rifle, 25's are real sensitive to twist rates. 65 grainer need a 1:14 twist and 120 need a 1:10. So we would need to deside what weight bullet we wanted to get before we know what twist barrel we wanted to buy. on second thought, it gets to complicated for a group buy. Two dogs mentioned 65's and I was looking in the 85 to 100 grain range.

Bill, I dont think the Single Six would have enough cylinder length for a 85 to 100 grain bullet. This is not to say that our Wildcat could not be adapted to other sixguns. On the otherhand, if you are going to a larger sixgun, why would you use the shortened case???
I think barrels come in lengths up to 30 inches. That will make several pistol barrels.
I would love to do a group buy, the main problem is that Miha, even tho he has gone full time, is pretty far behind. Something like a year and a half. Still, I could live with jacketed bullets for a year and a half to get a Miha cramer style HP mold....

Besides, I was just thoughing that stuff out there for food for thought. I could deal with a 65 grainer. I already have a mold. I had a Stevens 44 in 25-20 single shot with a 14 twist. Bill |

I have a Bowen OMBH in 25-20. Not sure of barrel twist as have not measured it. Have been shooting 85 gr. RNFP cast from BadMan Bullets. Initial problem was finding the right powder. Did not like some of the faster powders like 231, Titegroup etc. that would result in cases backing out and tying up the gun. Now shooting either H-110 (9 grs) or IMR-4227 (11 grs.) as that has taken care of the case set back issue. A fun shooter.
