    Thanks for the info Kg Was worried the the o6 cases was to small. Had forced a 7-57 case into it the shoulder was fine but the neck was little long

    Since i read some of you thread i'm gonna try the 7mm cases with a cast load. Need to get the sizing die for the lee .314 rn. how far down does it need to go? .310 or .309

    Aahhhhhhhhhhhhhhhhhhhhhhh, guns pics!

    I'm just making a search on "SANTA FE MODEL 1949". Interesting. I was afraid You got a barrel coming from an other gun in an other caliber.

    Also I found that on the net when you started the thread (it comes from some forum archives, maybe rec.guns; can't find it again of course...):

    ************************************************** *****
    Duane,
    I use 43gr H4895 with 140-150gr bullets in my MAS autoloaders with good
    accuracy and functioning. Velocity with 150gr bullet is about 100fps
    lower than the French Military surplus ammo, point of impact at 100yds
    is approx. the same

    Assuming you use due caution and approach max loads
    cautiosly, my limited experience would indicate that .308 Winchester
    data works quite well. 42.5 gr. of ACC 2520 behind a 168 Matchking
    yields about 2,600 fps, no signs of excess pressure and excelent
    function in my MAS 49-56s. Brass is former Lapua 6.5x55, resized
    w/ no trim, Winchester large rifle primers.
    -Tom
    I have used 39-43 gr of 3031 with a 150 gr Hornady
    SPBT in reformed Winchester Swedish Mauser and CCI
    LR primers. This was in a MAS 36. I wasn't happy
    with the accuracy of any of the loads. I'm going
    to try other powders in the future.

    The bore is supposed to be 308.
    (12/15, I should have written groove here and not bore; bore diameter is at the top of the lands. For example SAAMI specs for the 30-06 call for a .300 bore diameter and .308 groove diameter) .

    Do you have soft .32 bullets you can fatten with a hammer?You could then check bore and throat.
    I once bought a Lee "309" sizing die which gave me .311 bullets.... it was actually better for my use but makes it hard to tell you what to buy.
    As a guess, the throat on that military gun will take large bullets.

    You're welcome. Let us know how it turns out.

    P.S.: I was talking about 32(acp) bullets, but if you use freshly (wheelweight) cast bullets from your 314 mold, they will be quite soft.
    If the nose does drag/ride the bore you can cut it to limit friction. Maybe leave only two bands.
    I'm not sure it's necessary to slug the bore if you start with large bullets.
    I would'nt know what to use as a rod in such a small caliber. Wood can split and jam everything. I've capped wood dowels with brass cases in bigger calibers, and I slug handguns barrels with very squibby loads.

    And one more link:

    Toney,
    I bought an MAS 36 a couple years ago, it was in its original configuration and was brand new....can't remember the price but about $150. The MAS 36 does not have a safety on it, that's the way it was designed. Guess the designers felt that it was to be used by real 'riflemen'. One of the things that confronted me at the time was the cost of 7.5 French ammunition (some people have had their MAS 36's re-chambered to shoot the .308 cartridge).

    Couldn't find a supply of cases at the time but I did find that you could make 7.5 French cases from 6.5 Swedish cases....I did and they work just fine.

    The other thing that bothered me about shooting it was the odd looking bolt handle but after shooting it a while I've come to realize that it really is a good idea. The oddly bent bolt handle puts the bolt knob further back so that is more easily grasped. Not as good as an SMLE, but better than a mauser.

    Congratulations on your purchase and good luck.

    Default 7.5 mas

    you can resize 6.5 swedish mauser cases to fit the mas, bases are almost identical in size.

    Hi Toney

    I did some further reading at "rec.guns on the web, Google groups", "7.5x54" search.
    So far I found two posts mentionning tight barrels around .307 for the model 36.
    I quote:

    ************************************************
    "The old "HANDLOADING" by Wm.C. Davis, Jr. published by the NRA in
    1981 has some data on the cartridge. They meantion that 7.5 barrels
    are frequently tighter than the american .300 standard and that loads
    with .308 bullets should be approached with caution. I suggest you
    search used book stores or contact the NRA for this book."
    -Bob Hollingsworth

    ************************************************
    ..."My pristine model 1936 MAS measures .296" land diameter. That same 1936
    MAS slugs .3068" diameter for the grooves."....

    ..."Conventional reloading wisdom recommends jacketed bullet diameter be the
    same as groove diameter. Too satisfy my rifle nut curiosity, I obtained a
    custom bullet sizer from Lee Precision, specified at .307" ($25). Working
    with bullets from Sierra and Speer, I worked up reloads with virgin .308"
    bullets and with those run through the sizer. The sized bullets measured
    from .3072" to .3074" (springback). By measuring fired case expansion, it
    appeared that the smaller bullets could be driven from 100 fps to 200 fps
    faster than the .308" bullets with similar case expansion. No difference
    was noted in accuracy between the fat bullets and the sized bullets.

    My conclusion is that the French 7.5 can be reloaded with .308" bullets, as
    long as the reloader uses the same caution that he or she should use with
    any reloading activity. One can get a bit more safe velocity by squeezing
    ..308" bullets down a bit, but most will find the extra work superfluous."
    Al Rodgers
    *************************************************
    Of course we bullet casters live with different rules and look more for the throat diameter, but this is interesting information.

    Also I would like to clarify some technical vocabulary:
    In a previous post I wrote that the " bore is supposed to be .308".
    Technically, as in the SAAMI data, bore diameter means top of the lands and groove diameter means bottom of the grooves.
    For example SAAMI specs for the 30-06 say:
    bore diameter .300 (7.62mm)
    groove diameter .308 (7.82mm)

    So I meant "groove", or "barrel" in a general way.
    Which terms do you guys use and understand? I've spend too much time not listening to range talks and only trying to help beginners.....
