    My adventure on making 8mm mauser brass

    Let me preface this by stating ; Mods, if this belongs in the reloading section I apologise, and please move it. I figured it pertains more to anyone owning a 8x57 mauser though.

    So I got a great deal on a mauser, only to find out that it is seriously expensive to feed, and hard to come by. Onwards, with the quest for mauser brass! I am creating this thread to attempt to provide anyone else trying to do the same thing with information. I used my google-fu, which is admittedly marginal to average. However, most of the information was disjointed and some contradicted itself. This is my experience, with what works(ed).

    I started with a good quantity of 30-06 military brass with crimped primer pockets. I did this for 2 reasons, one, I allready had the RCBS primer pocket swaging tool from prepping lake city 223 brass, and Two; the brass doesn't say 30-06 on the bottom so I figure its less likely to confuse me or anyone else.

    After the first step of obvious cleaning in media to polish it up, I lubed the cases. The method I have come up with for this is extremely lube efficient, and doesnt require expensive lube. I am using the basic frankford arsenal case lube from midway, a gallon ziplock, and some plastic bins. I pump 2 squirts of lube into the ziplock, to coat either side, fill the bag half full of tumbled brass, pump 2 more squirts of lube in, seal it, and toss it like its shake n' bake for a min or so. This works the lube around and gets a very thin coating all over the brass. even gets some in the case mouths, but not much. I then dump it in a plastic bin for the lube to dry, and set it aside for at least an hour.

    Here is a pic of the whole setup, kinda.


    After the lube is dry, I remove the expander/decapping rod from my FL 8mm mauser sizing die, and full length size the brass. If you do not remove the rod, the brass will crush against the bolt that holds the rod.

    After the first sizing, approx. 6mm of brass must be trimmed off to bring the brass close to spec. I am using my own homebrewed version of a possum hollow trimmer in my drill press. I can only do 30~ pieces of brass at a time or the cutter will get too hot and not cut as efficiently, and this is a low buck setup. As a result, I am willing to take my time. I come back to it every so often and do a few more.




    I made a chip deflector out of a couple gatorade type bottles to contain all the brass coming out of this thing, spinning at 2000 rpm it flings brass shavings everywhere, and in great quantity.



    After the brass has been trimmed, you need to chamfer the inside and outside of the case mouth. This constitutes the major difference from normal case prep.

    From this point, you need to put the expanding/decapping rod back in the size die, and F/L resize the brass, do your finish trim to the length you want, and chamfer again. It is time consuming, but it beats paying darn near a buck a piece for mauser brass, if you can find it.

    Here is a pic of how the brass looks through the process. I will update this with additional pics once i get it all prepped, and loaded

    Pretty interesting concept you have going there. I would think that the reconstructed brass would thin out a little bit. Basically become a little frail and crack open on the casing. Have you fired many? Also, your work area looks like its well organized.

      Great writeup! Nice idea with the drill press trimmer. A friend and I have been making our own Mauser brass too. We use a small pipe cutter for an initial trim, full length resize through an RCBS die (it's long enough to do with the decapper/expander even before trimming) w/ beeswax based lube, then final trim with the Lee ball grip cutter. We give the necks a slight annealing with a propane torch.

      No problems with thin necks or splitting with full power loads, but I'm still on my first batch. I'll have to run them a few times to see if any fail.

      Since I don't own a .30-06 and I pick up all brass, I personally don't care about headstamp. All brass was initially free range pickup. Can't beat that!

        Why not just order some PPU 8x57?

          8x57 Winchester Brass 100 bag, $51. That is a hair over 50c per brass that gives you at least 20 loads. That works out to a brass cost per load additive of 2.3c, very fair.

            I hear what you are saying, but there is still the initial cost of 300 extra for the 600 pieces of brass I'm making. As compared, I got all my 06 brass for 50 and it should last the same number of loadings. From what I understand, military 06 brass is very durable and long lasting.

            In response to the thickness question, it actually ends up being perfect to slightly thicker. Some chambers may require the necks of the brass to be reamed but mine is fine.

              Because I cast and I like doing it myself, I'll be using the 215 gr karabiner mold and wc867 powder.

                I am interested to see how your lead holds up to 8x57JS velocities... or are we down-loading?

                also your brass was a smashing deal, 300 units of 06 for $50? Deal.

                  Not downloading appreciably, wc867 is a milsurp 50bmg powder tho so it is very slow. It's great for large bottleneck cases with heavy boolits because it gives a loooong push down the barrel instead of a sharp kick. I will definitely start with a lighter load and work up though but it should end up with quite respectable numbers.

                    I have found it cheaper to just buy 8x57, as it is easy to find. But good for you on making your own. I have done it a few times with 8x57 , but I usually make 7.7 Japanese when I goof around like that. Of course all I do is size a bunch of it, then trim it down with a Lee case trimmer and guide (less than $10 total). And I just use a hand drill with the cutter attached, so it usually takes about 30 seconds total per case. But to each their own, I suppose.

                      Well, not really worried about leading. My thoughts are based on the issues with lead bullets and rifle velocities, the bullet will actually come apart due to the forces involved as the bullet travels through the air. 8x57 comes very close to the kinds of velocities where that is reported to be true

                        Nice write up. I`m about to start reloading this round this makes it a little more affordable.

                          I just resize '06 with an 8x57 sizer die then cut close with a tubing cutter and finish up with a lee trimmer in the drill press.

                            you will get a pretty good amount of reloads out of those cases made from 30-06, I have some that I dont even know how many loadings they have through em but were made in 2005 timeframe when I was big into 8mm mauser.
