    7x57mm Mauser

    Been discussed before, but I like the 7mm Mauser and even though it's probably not the best candidate for a cast hunting rifle, I plan to try it out. I bought a '93 Mauser sporter this past year on a whim and have quickly fallen in love with it. I shot it a lot over the Summer, went through a 1K count box of gas checks plus a few other bullets I had already cast up.

    The deer load I've developed is a 287308 which was gifted to me and is factory hollow pointed. I cast these up from Larry's alloy, 50/50 COWW to pure with 2% of the wheel weight added. I'm shooting it with 30 grains of IMR 3031 which should be giving a little over 1900 FPS according to the RCBS cast manual I have. The bullets weigh 165 grains and that load will consistently shoot 2" three shot groups at 100 yards.

    Our two day antlerless segment is this weekend. I'll be hunting from tree stands and tend to make close shots at unalarmed deer. I hope to have a good report Sunday or Monday.

    The 7mm Mauser was used to take all of the most dangerous game in Africa at one point in time

    I have a special place in my heart for the 7mm Mauser. It's a great cartridge

    It's a shame that the 7mm-08 has just about killed it off in terms new guns chambered for the 7mm Mauser but there are plenty of good old rifles out there.

    The 7 x 57 is very close to a "do it all" cartridge. The 7mm-08 beats it slightly in terms of ballistics on paper but I think the 7 x 57 holds its own in the real world.

    Sako made a medium length action for a while and that action was just about the perfect length for the 7mm Mauser; I still kick myself for not picking up one of those actions back when they were readily available.

    The .308 Winchester, 7mm-08 and the 7mm Mauser are all fantastic general purpose rifle cartridges that really perform well over a huge range of duties. Of those three, the 7mm Mauser is clearly the oldest and the other two owe a great deal of their development to the 7mm Mauser.

    I look forward to hearing the report on the OP's hunting round.

    I too have a soft place in my heart for the great 7mm Mauser. I have a sporter that has an adjustable drop-in trigger with Remington style side safety, what I call a jeweled bolt, commercial bolt shroud on the rear of the bolt, and a walnut stock with a low cheek weld. None of it is especially expensive but it makes for a nice looking rifle. My best whitetail fell to it a few years ago (an 8 point). I am anxious to hear how your hunt turns out.

    Hope to hear how the cast in 7X57 worked.
    Not the 7X57 for me . . . yet (don't have it all put together yet) but my Husky 7mm Mag loves cast and I would gladly work on a softer boolit if need be.
    I have yet to shoot anything but cast through that 7 mm Mag, but roughly a thousand of those went where I sent them so far.
    I can always load the Mag comparable to 7X57 velocities.

    The 7 X 57 is never wrong

    I picked up a small ring mauser in 7x57 this summer strictly as a cast shooter but have not been able to spend much quality time with it . Have a nice hunt .

    eager to hear your stories. 7 x 57 is such a great cartridge in an old rifle.

    Don't have one but think a Ruger #1 with an International style stock would be the bees knees.

    Glad to hear that I`m not alone in liking the 7 Mauser. About 20 years back I developed this itch for a 7 Mauser. I had a DWM 98 large ring action for a start. I got a 24" fluted barrel put on then came the action work smoothing it to close as a butter feel as possible. A Timney trigger with side safety was added. Finally the AA grade walnut stock from Richards Micro fit was done and 10 coats of Tru - Oil later it was done. A Leupold 2 x 7X sits on the reciever. All I can say is this rifle shoots Hornady 139 gr. sp bullets like `A house afire`! I still hope to try a RCBS 145 gr. `silly wet` boolet thru it Good luck with your 7.Robert

    When I was young and knew so much more than I do now I was not impressed by the 7x57. Later in life I happened to trade for a 98 with a 7x57 barrel. I started shooting it and it shot quite well and was pleasant to shoot. Deer season rolled around and I took it hunting. A couple deer later I was starting to become impressed. It was light, accurate, pleasant to shoot and killed deer and coyotes very well.
    I was setting on several Turkish Mausers so I put a 7x57 barrel from midway on one. Turned the bolt, added a Timney trigger and a Gentry saftey. Put it in a blank from Brownells that I cut to fit me in a European sporter style with a schnable fore end.
    This was the first rifle I built completely on my own so it certainly holds some sentimental value. It has taken a pile of deer and coyotes over the years.
    I now consider the 7x57 to be one of the finest all around calibers ever developed.

    Good luck on your hunt.

    This rifle was rebarrelled, it is not the original military stepped barrel, but seems to have kept the long throat. I can seat that long bullet out far enough that nothing is below the case neck and they still chamber easily. I size mine to .287.

    The rifle is not a tack driver, but plenty good enough for what I want it to do and I like the dimensions of it so much.

    I like mine, it's a Rem mountain rifle 7x57. I don't shoot cast in it but it likes 140g B-TIPS. It's only slower than the 7-08 because of the U.S factory loads. Loaded to the same pressure as 7-08, it's a little faster (slightly larger boiler room).

    Good point on the SAAMI limits for the 7 x 57.
    Because SAAMI tends to set pressure limits based on the weakest guns chambered for a particular round, the U.S. limits are sometimes lower that what most actions can handle. The European C.I.P. maximum pressure limits for the 7mm Mauser are a bit higher.

    There are a lot of Mauser 93 and 95 models that are capable of safely handling the 7mm Mauser but it appears that SAAMI is worried that there may be a few that are not. Out of an abundance of caution SAAMI tends to set their limits using the lowest common denominator principle.

    My favorite mauser cartridge. Looking forward to hearing your report. I bought a brand new military barrel that was in long time storage. Some water got into the front 3 inches of barrel and I had to keep cutting off till I had a clean symmetric barrel crown. Ok, its now the fabled tanker carbine!
    Look twice, shoot once.

    Agreed ! Probably never needed another whitetail deer cartridge ever invented after the trusty old 7x57.

    i agree with poppy42 when it came out was touted as the best killing rifle ever invented . was used to hunt everything from elephant to buffalo. and everything inbetween. i think it will work great on deer.
