M1918 Chauchat: Testing a New Magazine

Today I am testing out a new .30-06 Chauchat magazine converted from a Johnson M1941 machine gun magazine. The workmanship on this new mag is excellent, and much more extensive than I had initially realized would be necessary. This had the side effect of also making is a very expensive magazine to have made properly.

Unfortunately, the cost of that project has become unjustifiable. I initially wanted to have 5 or 6 of these, to allow me to have about 100 rounds loaded into magazines for competition use. Instead, I will be using a French 8mm Chauchat for anything requiring more than 10-20 rounds of ammunition, and leave this gun for more historical uses. While 8mm Lebel ammunition is expensive as well, I have a substantial number of good military magazines for it, as well as a much more accessible market of spare parts should anything break.

I know a bunch of people will ask about 3D printing magazines. The reason that is not practical is because all of the clearances in the gun were designed around a magazine made of thin metal. In order for a 3D printed plastic to be strong enough to withstand the force of a stack of ammunition under sufficient pressure to feed reliably, the plastic would need to be substantially thicker than the original steel design. And there is not physical space inside the gun for that – the clearances between the bolt head, magazine feed lips, cartridge pusher, and barrel extension don’t allow it.

    • Okay, let’s back up a bit. You’re comparing apples to oranges. The Lewis gun was intended for TEMPORARY STATIC DEFENSE, not SMASH, BASH, AND SHOOT THEIR BALLS OFF. I haven’t read any accounts of British or American troops spraying down German trenches while literally ON THE SPRINT. Changing pan magazines is a fiddly two-man job and makes you a very good target (for field guns) if you’re standing up and using the Lewis as a machine rifle. I would rather recommend a Hotchkiss light machine gun perhaps if it were given a wooden hand guard and if it were modified to feed from detachable magazines as opposed to feed strips. Of course, I am assuming that the Browning Automatic Rifles have not arrived yet.

      Did I mess up?

  1. “While 8mm Lebel ammunition is expensive as well, I have a substantial number of good military magazines for it, as well as a much more accessible market of spare parts should anything break.”
    Is 7.65×53mm cartridge (known in U.S. as 7.65 mm ARGENTINE MAUSER) available at U.S. market? If yes, then Belgian version of Chauchat firing that cartridge: http://www.historicalfirearms.info/post/166619060194/the-belgian-chauchat-throughout-the-first-world
    should be very sought after, but sadly also being rare. Are there any known existing examples?

  2. What was the cost on the modded Johnson mag? Also you could look to having a sheet metal worker look into making mags for it, instead of a gunsmith. Most gunsmith I know of work well with milling steel and not working with bending sheet steel.

  3. Thin plastic sheet (non) metal 3D printed magazines would work no better (and likely MUCH worse) than original century-old-already-wonky examples of veteran magazines.
    There’s a reason certain items…you know what those in your own experience might be…are made of metal…
    If you need to negotiate with a sword, best be done with other than a polypropylene NERF one.
    (Homework for 3D printer aficionados: Explore the doubtful relationship between “THERMOplastic” and “FIREarms” and reason out why this not be the best idea. Duh.)

    • “There’s a reason certain items…you know what those in your own experience might be…are made of metal…”
      Magazines were generally steel, but then maybe some other metal (which is not steel) might be used instead? Possibly easier to machine? Any ideas?
