Argentine Mauser from 30-06

[WRideout]

I'm with Reg on this. I make my 7.65 cases from 30-06 and 270 brass and have never turned or reamed the necks and had no chambering or other problems.

In the dark ages when my only rifle was a sporterized argy, i made cases from 30-06. i did have trouble initially with overpressure loads, but i had not acounted for the possibly thick brass reducing the internal case volume, or the certainly thick neck wall that i did not ream or thin.

I recently aquired my first 1891 Mauser.
I don’t have 7.65 Mauser dies yet, but long ago I shortened a 7.7 Japanese FL die so that I could load 7.65(neck size) for a 1909 Peruvian that I had at the time.
I used 30-06 brass at first, moving the shoulder of a trimmed case back until the bolt will close.
For grins, I also converted some 7x57 brass that had previously been converted from 6mm Remington brass…..
The shoulder needed to move forward a bit on these, so with 3 grs of AA#2, paper, corn cob tumbling media, and old orphan primers- I fireformed them in vertical position.
Thank You, Push Feed Mauser!
I’ll post some pics later on.

Here are the formed cases next to a surplus case.
When my proper dies arrive, I’ll just use 30-06 brass since I have quite a bit of it.

I really like the 7.65x53 Mauser. I built a sporting rifle with a 1908 Brazilian Mauser action and a new/old stock military barrel off a 1909 Argentine. The rifle looks kind of goofy with that 29" stepped barrel, but when it shot the first 15 rounds that I fired through it into a group that you could cover with a quarter at 50 yards I decided that this dorky looking rifle was beautiful. I like the 7.65x 53 so much that I'm planning to build a second one on a 1895 Chilean action. In the beginning I did form some cases from 30-06. I used Lake City brass and had to turn the case necks. Not long after that I chanced on a treasure trove of new Norma brass that had sat on the shelf at a Mom & Pop gun shop for so many years that they had it for sale at give away prices (I bought all they had). I won't need to be forming brass again for a while.
As a side note, I've had some really good accuracy using the Lyman #311284 powder coated and sized to .3125" I have been using a charge of 24 grains of Shooters World Buffalo Rifle (almost the same as 5744). This load has been amazing in my rifle, and shoots better than I can aim. I was wondering if anyone has tried the RCBS 30-180-FN in 7.65x53? Powder coated and sized to .3125" I'm guessing that this might be a good bullet in this caliber, but it will be a while before I can get some range time to find out. Just wanted to know if anyone's tried it?

Haven't shot mine enough to get to know it. I do form cases from .30-06 brass. I use a course disk sander to shorten the case almost back to the shoulder, run it through the die, then trim to length. Works well.
