Reload Data for 7.65mm Argentine Mauser

[Linus]

My manual doesn't have the specs on IMR powders so can someone give me the data for the 7.65mm Argentine Mauser using IMR 4895.
Thanks,
Linus

You can go to Hogdon's web site and get it.

Thats what I normally use but they don't have the data for the IMR 4895. I know it exists since I've seen in in the manuals but I don't have one and I'd appreciate it if someone gave me the data for just that powder.

What bullet?
I can run a quickload pass for you...

Cartridge          : 7.65 x 53 Arg./Belg. Mauser
Bullet             : .311, 180, Sierra SP 2310
Cartridge O.A.L. L6: 2.992 inch or 76.00 mm
Barrel Length      : 24.0 inch or 609.6 mm

Predicted Data for Indicated Charges of the Following Powders.

Matching Maximum Pressure: 56000 psi, or 386 MPa

or a maximum loading ratio or filling of 105 %

These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.

Thanks, 3021ft/s is impressive but what is the Min and max charge thats safe?

[ar15barrels]

Thanks, 3021ft/s is impressive but what is the Min and max charge thats safe?

Per the warnings, the max charge is listed above.
I ran the simulation at 56,000 PSI which is just under the max recommended pressure for that cartridge.
Reduce by 10% and work up as you would any other load.

[Linus]

Yeah thats what I was thinking but "!DANGEROUS LOAD-DO NOT USE!" at the end kinda scared me. Thanks again though.

Those warnings are user configurable.
I think they say "DANGEROUS LOAD-DO NOT USE" anytime you are within 5% of max pressure.
