1891 Mauser 7.65x53,

[doubled]

I recently got a 1891 mauser it isn't marked with any caliber any where on the gun, by searching THR I found out it is a 7.65x53. I also discoveed that 30.06 can be trimmed down and be used in the Mauser.
Can any one tell exactly how this is done and what tools I need to do this, I do reload but have never modified brass from one caliber to the other, I reload with Lee dies and press, and have a mini Lathe, and all the mics and such as I need, any inforemation would be greatly appreciated

doubled...This is reletively easy, even I have done it! I use Lee dies and trimmers.

1. Run the 30-06 case through the 7.65x53 sizing die.

2. Trim the case to length for 7.65x53. Cut the case a little long with a hacksaw then trim to correct length with the Lee case trimmer and deburr.

3. Load and fireform the case. I generally use a cast bullet and low to medium velocity load but you can use jacketed full power loads if you want.

4. Retrim case if necessary and you are ready to use.

It is surprising how many cartridges can be made from the venerable 30-06, guess that's because it parent was the 7mm Mauser.

Good luck

A whole lot easier to just buy brand new virgin brass from Graf's. Yugoslavia is also loading for this caliber in new production brass, boxer primed, and non-corrosive. I've used it and determined it to be tremendous quality.

ammoman.com (free shipping) has the Yugoslavian 174gr FMJ-BT for $10/box of 20, or $99/200 rounds. I bought some of this before buying Graf's brass and loading my own. I load the Graf's brass and fired Yugo brass with Hornady's #3130 jacketed round nose .312" over 43.0gr of IMR4064 for ~2475fps out of my sporterized 1891 Arg. Engineers Carbine.
