    Greetings, Gentlemen,

    Won on auction. One of those "buy it now for $230.00 deals".

    When I received the 73 revolver, I inspected it very closely for any areas that might need my attention before putting it in service. I found 4 items. Probably the most serious being the muzzle had been struck hard enough on the bottom to actually create a slight out of round condition of the bore. Very carefully using a hardened steel rod, of slightly less than bore diameter, an oak die with a half round notch same diameter as barrel O.D., and a hydraulic press, I was able to restore bore roundness.

    Next priority item was the cylinder lacked about 4 or 5 degrees of coming to full index against cylinder stop during operation. The surface of the hand that contacts the ratchet at full cock was worn. Got out the torch and hard faced it approx. .020" thick. I then carefully filed it down with a diamond file, then polished the surfaces. When finished, .008" had been added to the thickness. Now it indexes perfectly, and is as smooth as roller bearings.

    Only things left to do were to clean the outside surfaces and point up the checkering. That being done, we will get to the important part of the story.

    I have finally reduced the handloading of the 11mm French down to a few basic steps, along with what I feel are the proper tools and components to produce a satisfactory cartridge that gives excellent power and accuracy in the 73 French Ordnance revolver.

    I measured the chambers, and they are .473" at base, .451" at throat. The .44 Mag. case base diameter is .453". The .44-40 case base diameter is .462". I opted for the .44-40 case as the .44 Mag. case rattles around too much in the chamber. I trimmed the rim to .040" thick and O.A. case length to .740".

    Walt Melander of NEI Handtools made the mold for the .451"-220 gr. heeled bullet. ( Sad note: Walt died on his way to work just a few days after finishing my mold.)

    Resize fired cases in 44-40 sizing die.
    Run a .44 Spec/Mag sizing die down the case only as far as the bullet will be seated.
    Use .44 Spec/Mag expanding die. Belling mouth just enough to prevent shaving bullet.
    Install Federal 150 large pistol primer.
    I charged with 5 gr. Unique powder.
    Seated bullet with my .450 Adams seating and crimping die. No crimping can take place.
    I crimp case in my special 11mm crimping tool that fits my Lyman mold handles.
    Apply Lee's liquid allox and set aside.

    Fired in my shop. That's the reason for target at 30 feet. Chrono at 10 feet from muzzle. Velocity average: 740 fps. Fired 12 rounds.

    I know, I pulled a couple shots out of the group. But when you're 68 years old, you're allowed to do that.

    Got one missing the loading gate, otherwise perfect, last week for $100.00 US. This is the third one I have found in Pawn Shops here in Birmingham since 2001. I had no idea that they were going to be so popular!!! So far I have one "F" three "G" and 2 "H" series, mostly from Gun Shows in this area and the aforementioned Pawn Shops. Since these guns are legal in France, I suspect that the foreign buyers will be snapping them up at US Shows.

    Greetings, Dale,
    Seems there is quite a few out there. Sounds like you are particularly fond of them. Do any shooting with them or just collecting? Really a robust little revolver. I am a collector of early, large bore, cartridge revolvers. I get a great deal of enjoyment and satisfaction from restoring and shooting the old revolvers.

    Well, somebody has to do it. 1873 revolvers do indeed fetch a lot more in France, as you can see on , and I dare say French dealers are buying them in the Us. But it doesn't seem to be showing much in terms of prices yet. They must surely be the greatest bargain available in antique firearms.

    My second-best 1873 has the same condition of the cylinder, although due to a mismatched cylinder in this case. I have made a very similar complete replacement hand, for my Dutch M1873, but it seems better to use an existing part if you have one. Not everybody has acces to hardfacing equipment, or would care to trust such a crucial part to a non-gun welder. An alternative I think would work well, though, is to silver solder a piece of steel to the top. A piece of high-speed steel wouldn't require hardening, and thus would let you out of the danger of loosening the added portion.

    Ralph: I shoot them occasionally in my yard, I live in the woods, so no one cares, I have not got into reloading yet...Is there an equivalent smokeless load for this gun??

    John: I have some of the Mle 1874 Revolvers too, also the Webleys and the often overlooked Spanish 455 Revolvers from WW 1....

    Back up to the message above the photo. Smokeless load is described there. If you like old revolvers, click on this thread.
    I don't think it got read much. Must have titled it wrong.
    Regards, Ralph.

    Ralph, I read your other post on Galands. Can you recommend anyone who can perform similar repairs to my two Galands? I have one in 9mm and one in 12mm.
