Well, the board is either fixed, or it's going to run terribly. Cross your fingers and hope for the best. I'm at my technical limit right now.

Reloading for 1909 Mauser

#1 Post by Hippycrowe » Wed Jul 25, 2018 9:10 pm

Have you slugged your bore? These rifles were made by both Germany and Argentina. Every German-made 1909 in .30-06 I've seen had a true .308 bore. The Argentine bores vary more it seems, but if you have a true .311" bore in a rifle chambered for .30-06 then you could also have a Modelo 1909 rechambered from 7.65 Argentine. I think you need to know exactly what you have before going forward.

Running a .311 bullet through a .308 bore will likely not be accurate and will probably accelerate wear.

Since you have M1 Garands I would recommend simply using the standard USGI .30-06 load of 49.0 grains of IMR 4895 behind a 150 grain flat base or BT bullet. That load has proven to be very accurate for me. YMMV.

The military model 1909 was made in 7.65x53 with a groove size of .311 + . The rechambering [ only ] to 30/06 was done by the importer , the barrel was not changed . Changing the expander will work ok , or just neck size with a 7.7 Jap die . Also , if the bore [ lands ] is tight enough a .308 bullet with a soft jacket or a long bearing surface may shoot fine .

You probably already know this but in the event that the bore proves to be .311" (and I think it will), PRVI Partizan makes 311" 150 grain FMJ-BT bullets that cost less than $30 per hundred. Again, for IMR 4895 powder with that bullet I would start with the proven powder charge of 49.0 grains. Just my 2 cents worth.

I may have a barrel made for it some day in 30-06 just for fun. I will probably load to 7.65 data I am just putting holes in paper no need to waste powder. I have read the 1909 model was very strong high quality material. I did find a pretty nice 7.65 1909 barrel on GB for $50
