Pietta 1851 Navy problem

The notch in the catch isn't deep enough to secuely hold the loading lever. Square up and deepen the notch & it should stay up better.

That's one of the reasons why I shoot '61 Navies now days. The catch has a different profile with a deeper notch than the '51s.
 
what he said, ditto

had the same problem with my newest Remington, and my old 1851 Navy-

file the notch deeper on the retaining latch groove

that's the little thing that hangs down under the front of barrel, and when you press the spring loaded latch in on the loading lever, it catches in the groove in that round part under the barrel

that notch that the latch catches into- take the thin side of a file, and grind it deeper so the spring in the loading lever, can fully push the latch into it

that fixed my 1851, but my newest 1858 still drops the lever

another thing you can do, is put a stronger spring in the loading lever latch assembly
 
Milder loads help as well. Not sure how many grains you're shooting but my 1851 seems to like no more than 30-32 grains for best accuracy and functioning.

Cheers,

30gr is max for the 1851 design, Pietta lists 15grs as max for their guns. Might be part of the problem.

25gr may fix your situation, and prolong the life of that revolver.

Pyro, FFFg BP, T7 or whatever it be - 30 volumetric grains is a max charge for the 1851 design. And a double charge for the Pietta design by their specs. Back the charge off a bit and see if the lever drops still.


You are doing a volumetric charge right? If you're weighing out 30gr of PyroP, the charge would be equivalent to about 38gr of real blackpowder.
 
i use the brass powder measure and fill it to the 30 capacity. i have also noticed i cannot hit the broad side of a barn with this Pietta Navy. I am a fair shot with my 1873 SAA, 1872 Open Top, etc...but even at 7-10 yds, I miss the steel completely with this Pietta.
 
Reduce your amount of powder. Unless I'm blind, you havent said what Caliber your '51 is. If it's a .36, 20 grains is all you really need. If it's a .44, 25 grains is more than sufficient. Big, chamber full charges are fun; but they aren't very accurate.
 
no - i neglected to mention the caliber. it's a 44...so i put .454 sized hornady balls through it.
