It is Finished

[King Medallion]

Today I took delivery of the final caliber for my collection of 76's, the 40/60! Took awhile but I finally got them all! Uberti of course, but that was my goal. Came with Lyman dies, 20 factory smokeless rounds and 120 FF BP rounds. Enjoy a few pic's.

can I assume you will be ordering again from gunstockcover.com ? 

[King Medallion]

Ordered it the same day I bought the rifle.

Here is the one box of factory smokeless ammo.

Looking forward to the shooting report.

Anyone have any idea what these smokeless loads maybe loaded with?  Seller said they are factory loaded. Should I trust that? I can call my reloading room a factory. The black powder loads too, Should I trust that, or break them all down and reload them myself?

Mashburn down in Texas does load ammo for a wide variety of hard-to-find calibers.  But I have no idea how well they do it.  I would suspect, though, that it's intended to be safe in any good condition rifle including an original, which means you have a margin of safety shooting it in a modern Uberti.  But that depends on halfway-decent loading practices with smokeless.

From the green color of that box and the fact that it says 60 grains, I would wonder if it's actually black, not smokeless.  Of course, the box could have been reused for other smokeless factory/small commercial ammo because it looks neat.

Since you have dies, you might consider pulling one bullet and seeing what you have.  If it's black powder, that answers that question.  If it's smokeless, given that it's only 20 rounds, I personally would probably pull them all and reload them with my own loads, either loading black powder or loading my own smokeless so that I know what I'm shooting, as much for the useful feedback on accuracy etc as for the safety.

As to black powder, I think it would be very difficult to do anything in the .40-60 case that would be dangerous in a Uberti 1876.  You might try pulling one to make sure it's black, and to measure the bullet to see that it's not grossly undersize.  If it turns out to be well under groove size, then you may have a bullet-pulling operation on your hands, although if the bullets are dead soft you may be able to get away with quite a bit.  Could depend on results.  I expect you'd be perfectly safe reusing the black powder, although you could consider loading your own black powder (so you know it's consistent and know exactly what loads produce the results you're seeing on the target) but reusing this for some short-range pistol ammo or something.  I know it's 2F but it's not like that's actually going to hurt a .45 Colt or the like.

Just my .02 and your mileage may vary etc.
