7mm Mauser Ammo

[53caddy]

Does anybody know where I can get some surplus ammo at? Just picked up a new gun and would like to try it out.

[gregintenn]

Surplus 7x57 supply dried up many many years ago. Your options are to shoot factory ammo, or load your own. Option #2 is much more cost effective.

[Moped]

A shame too,  It's a great round!

[1gewehr]

Small quantities pop up from time to time.  You just need to keep your eyes open and grab it when it's available. 

 

Here's some:

Samco is the only game in town. Corrosive and nasty looking. Prob ok in a bolt gun. I'd be cautious in a semi.

Grafs has 7mm privi in stock usually

Well I bought 400 rounds to shoot in a FN49. Hope it doesn't screw it up.

[austin7.62]

It'll be fine. FN49s are SWEET.

[Hershmeister]

Let me know what condition the ammo was in and how it shoots in the fn. I recently picked up a vennie and if samco's ammo is GTG then I'll load up on some. Thanks!

Will do. Hope to get it shipped soon. At 20 cents a round I couldn't refuse trying it out.

[austin7.62]

Good luck. SAMCO usually takes forever to ship, not trying to crap on you, but it took them forever to ship a friend's Persian Mauser. Might be different with ammo though.

Dunhams in Columbia has some in stock now. I saw it tonight.

[CelebrateWood]

A couple of weeks ago they a lot at Bass Pro Shops at Opry Mills. None of the 8mm I was looking for but plenty of 7.

Just to let everyone know I just now finally recived the ammo from Samco. Pretty dirty brass. Just thru a couple handfuls into the tumbler lets see how they come out.

Ummm you really should not have done that.

How long did you tumble it for?

Putting loaded ammunition into a brass tumbler will cause the powder to grind together inside the cartridge casing, the result of which can be a finer grain of powder than originally intended & a much faster burn rate.

This can & will cause much higher chamber pressures & if the pressure gets high enough can damage or even destroy a firearm, &/or the person shooting it.

[Hershmeister]

A brief while in the tumbler shouldn't prove harmful. Now I wouldn't leave them in there for hours at a time....

About a year ago, I bought 400 loose rounds of 7x57 from SAMCO. Incredible deal. About HALF of it was WINCHESTER BOXER Primed...!!! The rest was South American stuff from the 40's and 50's that has a short delay when firing it. The Winchester stuff fires like normal ammo. I am killing myself for not buying more. They only ran out about 2 months ago (March 2013). I at least have about 200 rounds that I can reload. For anyone else out there who has bought this ammo from them and want to know if they have any of this Winchester Boxer Primed stuff, it says on the bottom of the caseing "WRA  7MM". There is no date on the caseing. It is absolutely obscene how much NEW 7x57 costs. About the best you will do is $1.50 a round.

Do you have any proof of this? My tumbler gently rolls brass around in a circle. It can't be as bad for it as who knows how many thousands of hours/miles it has been hauled around it how many countries in the back or a truck, in a plane, boat, horse, camel, etc.

I am not sure how I'd be able to provide proof of this to you other than I guess you could tumble some loaded ammo, pull the bullets & measure the grain sizes of the tumbled powder after/at various time intervals.

Or if you are that sure it won't effect them & you have a chrono you could tumble a few for awhile, see if there is a change in velocity when you shoot them, or you could just stay on the safe-side, take the word of some semi-anonymous forum poster, who's been shooting for 35+ years & reloading for 25+ years & who is just trying to keep potential bad things from happening to his fellow forumites.

*shrug* I shared a bit of safety info, what you all do with it is completely up to you, heed it, ignore it, test it, but whatever you do .. please be careful doing it.

I have done multiple research on tumbling live ammo. Everything I have found scientifically points to its ok to tumble live ammo. Here is a link to a good write up.

Well like that fellow on ARFCOM you might get away with it ... up until the one time you don't ... shining up tarnished cases on live ammo by tossing them into a tumbler seems like such a trivial reason to take such a tremendous risk IMHO.

But to each their own, I hope I never am in a position to say "I told you so" because that'd really suck, especially if you lost an eye or some fingers or something.

[Garufa]

Pretty ammo does not shoot any better or worse than ugly ammo. 

 

That's all I have to say about that.

Only one logical way to shoot 7x57.

Roll, roll, roll your own. Crimp the end and then........

Problem is finding brass. Also in the fn the brass flys forward and gets lost pretty quickly

[Hershmeister]

Grafs has brass and bullets. Better yet, buy privi loaded ammo then reload those cases

Bah!
Make it! You can form it from 30/06, .270 etc.
