Gregorelli & Uberti 1851 Navy

[LonesomePigeon]

I have an old Navy Arms 1851 Navy by Gregorelli & Uberti with no proofmarks so it's probably from about 1959. I ordered some short Pietta 6-.75mm nipples from Track of the Wolf, part number PIR-I.  I think these should be the right ones but there is just a tad bit of resistance when I try to put them in. It's wierd because I tried some old Pietta nipples that came off my circa 1986 Pietta 1858 Remington Deluxe Model and they went in just fine with no resistance at all so I don't know why these new Pietta nipples won't go in just as easy. Maybe I'm being too delicate but I don't want to risk messing up the threads on the cylinder. Does anybody have any personal experience with replacement nipples for a G&U 1851 Navy?

These are the ones I'm talking about that I got from Track of the Wolf:

Personally, don't have a clue about the "old" Uberti you have.  However, "normally" Pietta and Uberti do NOT play well together.  Don't push the threads.  May strip and then your screwed until you find a "fit-able" cylinder.  I'd shop for some different nipples.

I have an early 36 cal Uberti Remington with 6X.75 nipple threads (like Pietta & ASP/Euroarms) and two later 44cal Remingtons with the 12X28 threads Like ASM.

Ok I am going to order some .225-32 and see if they fit better. It seems that over on the Centaure forum in this thread http://1960nma.com/BB/viewtopic.php?f=5&t=176&sid=e18bdb071abc2acdc48bcabfb244ce01 there are some different opinions on whether the 6-.75mm or the .225-32 are the best when replacing Centaure nipples. So maybe it is the same with Gregorelli and Uberti where some of them want the 6-.75mm and some of them want the .225-32.

I have an old [XXIV] Uberti 1861 Navy. After seeking advice in this forum I bought M6 x 75 thread, "Fits Euroarms Revolvers" , TRESO product No.  11-50-146. I believe the change-over came with the Colt Series 2 production.

I received my .225-32 Track of the Wolf nipples(part number: POC-I) today. The threads fit both my Gregorelli & Uberti 1851 Navy and my Centaure 1860 Colt Army correctly. However, the cone length of 0.300" is a bit too long for the GU 1851 Navy, when the caps are on they scrape the side of the ring on the recoil shield. The cone length looks correct for the Centaure 1860 Army but I need a replacement wedge for it before I can say for sure. Incidentally the .225-32 nipple is also listed as being the size for the original Colt revolvers.

Does anybody know of a source for .225-32 nipples with a cone length shorter than 0.300"? Track of the Wolf does not have any listed that I can see.

I use .225-32 nipple in both of my 2nd Gen. 1860's & my  2nd Gen 51 NAVY,
At the time,  assumed they were the same being 2nd Gen. and Navy frame based so in ordering I just got the same sets
I seem to recall a drawing and TOTW part # for like threads , but cone length option ...
That was so long ago , early  90's my memory & fantasy are one in the same now...

I do clearly remember , I did chuck up the set for the Navy in a drill
and gave them a spin,  an trim with jeweler's file and polish.
I used exclusively RWS Caps , Green label for the Army's & Red label for the Navy , this was my solution back 25 years ago.
These same nipples and the OEM Nipples are still used in these guns today...
Every use,  they are removed cleaned , a dab of anti seize applied and reinstalled ( probably intermixed with OEM gun specific years ago ... The spares kept and used alternately in the same specific gun (each gun has 2 sets ) never need anything else really...

Though I did buy (Ampco) nipples from the Log Cabin Shoppe' long ago for my
Sharps Carbine., I can't recall if they were TRESCO brand. 
I've never used the brand in any of my Colts 2nd Gen. , never having issue with the OEM or spares form TOTW...

Not scientific and other's mileage I'm sure varies ... that just was me and what I've done... I've had the guns 35 years , one does have Kenny Howell Conversion in it now however ... but that whats worked for me all these years...

Someone(s) may roll their eye's  at my solution , which is fine ... it has worked for me , and I didn't mess with fixing beyond what was not broken .. as I said " other's mileage may vary " ?

I would suggest you look thru the selection at Dixie Gun Works.

I have replaced the factory nipples in all three of my c & b revolvers with TOW's nipples.  The replacements for my 1849 Wells Fargo .31 cal fit perfectly.  I had to run the nipples for the 1860 Army through an appropriate metric die and then they too were perfect.  The newest nipples are for my 1847 Walker ...all three revolvers are Uberti's BTW...they were tight but went in without galling and bottomed nicely.  A test with caps on all the nipples firing as fast as I could work the hammer was conclusive...great nipples.  No jamming of fragments into the hammer well, and all caps left the nipples and ejected out of the right side of the frame.

I may have to invest in some new nipples for my .44 Remmies. I didn't shoot "Frontiersman" at a recent SASS Championship as I had a few failures to fire at out club's annual match. Discouraged me, as I'm used to them going "Bang!" every time.

Cap & ball is as Cowboy as it gets, even more so than brass BP - IMHO.

.225 X 32 only fit original 1st gen Colts...

[LonesomePigeon]

Yes the .225 x 32 are made for original Colt's but they are the same thread size as my Gregorelli &Uberti 1851 Navy and the Centaure 1860 Army. However the cones are too long for the G&U, I think the cones are just right for the Centaure but I have not fired it yet so I'm not 100% sure of that.

I have had to run a die over the threads of Treso nipples on some editions...  Checked them in several cylinders to be sure, but apparently they wear out tooling occasionally.

The Ruger nipples fit the Uberti, incidently, but have slightly shorter cones.
