Anyone have any reloading data for the 7mm Mauser AI?

i dont have mine handy, but the handbook for reloaders, by PO ackley, sure does

I use in my rifle (98 Mauser VZ24 action):

139 Hornady Interlock
52.5 - 55.0 H4350

Velocities, 2924 low, 3095 high, avg. 2997.

Safe in my rifle, no pressure signs. Use at your own risk.

Get Ackley's book.

You can add about 5% to a reloading book load for the standard 7x57, and it will be milder than milk soup, so just start working up one grain at a time..

There is no set max load, you must find it for your particular rifle, a much guarded statement by reloading manuals, they are scairt ta death of law suits...but I am a firm believer to know where max is with ever rifle I own. I may not load max for my shooting but I sure want to know where it is with any given load in any caliber...This may or may not be for everyone, I don't know so I speak only for myself.

Ray,

100% with you on this and exactly what I do with any rifle of my own. I've usually found maximum can be anywhere from 3-5 grains above published max loading data in whatever reloading manual I'm using. Then I back off a grain or two to where I feel comfortable with pressure, accuracy and lastly speed.

I've just gone through this procedure with my 6.5mm SAUM, but then as it is a wildcat it was absolutely necessary, though I'm still a firm believer to find maximum even with a factory cartridge and published max loads.

I think any serious reloader would do the same.


Michael.

when I got my first 7x57 Ackley I was scared to death about loading data.
I knew my rifle would handle higher pressures than the 45-k the books all kept showing.
I basically started at the top of the normal data with a slower powder for the cartridge and kept going up.

I like the hornady interlock, and I know it's muzzle velocity for best performance tops out at about 2900 fps so I started heading that direction.
I hit right about 2880 and an accuracy node using RL-19 and the rem 9-1/2 primer in Remington brass.
that's been the only load I have needed since.
it's been stellar on deer works on elk and has taken a moose as well as some coyotes and a few grouse.
I can run the velocity up higher and shoot other bullets faster.
I just don't see any reason to bother, I have all the accuracy I need and the bullet does it's job when it gets there.

Mr. Brown, eabco.com has tried to stock the Ackley set of books as available. Mr. A liked this one and much data. Rivalled the .270 before WW II with powders then available. Imp just made it better. Luck. Happy Trails.

51gr of reloder 19 is the magic in my 7x57 with a 140gr TSX bullet, its a book load in the Barnes manual. you will like go higher with more case capacity
