Longest Barrel 1873 Rifle in .357

[icemaster109]

I was wondering what is the longest barrel 1873 rifle in .357? Does anyone produce it? I know there are some 1876s, and 1873's that are close to 30 inches, but most are in larger calibers. Particularly the 1876's, which are in rare rounds (45-60?)

I believe the longest barrel '73 currently produced is 24" octagon.  The 30" rifles are made only in 44-40 and 45LC.  In the past Uberti made a '73 musket which had a long round barrel.  I'm not sure if those were made in .357.

The Muskets are the same deal.  Only available in .44-40 and .45.  Main reason is weight.  I have a Musket in .44-40 and that sucker is heavy.  Would be very unwieldy in .357.

Not sure why you want the longest barrel.

If it is for more velocity, here is some data worth looking at:

http://www.ballisticsbytheinch.com/357mag.html

Past 14 inches long not much happened velocity wise. In fact, in a few of the loads the velocity appeared to drop off past 14 inches.

There is data for lots of pistol cartridges on that same web site. For the most part, after 14 inches thee was little or no gain. In some calibers, things went down hill after 5-6 inches.

I guess it sort of makes sense. Pistol cartridges were originally designed to be fired in pistols. The case capacity and the classic powders were all designed for shorter barrels.

That's not to say that with handloading some improvement geared specifically at longer barrels can not be made over factory ammo. Looking at load data specific to the 14" barrel T/C contender or specific to rifles would help. Heavy bullets (180 gr), slow powder (H110) would use a bit more barrel.
