Help Me With Loding 10X47R
#385094 - 03/06/24 03:16 PM

I have a few 9.5X47R brass and can form the brass necks using my 41 magnum pistol dies and blow the brass out enough with some blanks.

According to some specs for this round it takes a .401" diameter bullet, the same as for the 40 S&W, and I have 200gr and 220gr cast bullets that diameter. I hope I can find a very old partial carton of Ipco Grease Wads to place under the un-lubed bullets.

Does anyone have any load data for this round?

Thanks,
Bruce

I have a double rifle in 11.15x47R which uses a 0.439" bullet. For brass, I mainly used 9.5x47R brass fireformed in my rifle.

I have also used 45/70 brass run thru a shortened 43 Mauser sizing die and with the head thicken to that of a Mauser A head. That brass is trimmed to 47mm and then fireformed in my rifle.

I have loaded the case with a case load of Triple 7 and either a PP 250 gr 0.430" bullet paperpateched to 0.439" and also a 386 gr 0.439" bullet. I have also used 22 gr of 4198 to push either bullet.

Now with your 10x47R, I would think that a load of 20 gr of 4198 and a 220 hard cast bullet would work.

Back in '81 while I was staying with a friend in West Germany we were loading for his little Belgium double hammer gun with 24" barrels chambered for the 10.75x47 cartridge. We swaged 265gr 44cal Hornady bullets from .429" to .423".
From memory we got reasonable accuracy and regulation with the load we finally settled on.
My friend eventually immigrated to NZ and my notes taken back in 1988 show our load as being 45.0grs of Rottweil R902 with a RWS primer in original cases with the Mauser A base head. Chronographed MV of this load was 1588fps.

I have a shaky memory that Rottweil R902 is similar to Reloader#15.
Can anyone confirm this?

My burn rate chart shows R902 on same line as IMR3031 with Reloder15 one line back (faster) from IMR4350.

luv2safari,
Is your rifle nitro proofed? If not, I suggest that you remain with either black powder or NfB loads.
