Morning all
I manage to lay my hands on a M72 MS in 9.3x64 Brenneke, and need a load please for this caliber?
Although its not a pure MS like my other rifles, I got it for a good price... Would love to get a older model in this caliber, but as far as I know there is only 1-2 in SA that I know of?
I have 100 new RWS brass, 286gr Nosler Partitions, 286gr Horndady SP Interlocks, and 286gr PPU SP bullets. I would like to use powders that is available in SA if possible. Currently I have the following available:
Somchem S335, Somchem S365, Somchem S385
Norma 202, Norma 204, Norma MRP
Vihtavouri N540, Vitha N550, vitha N560

Might be able to get IMR or Hodgedon but would only go that route if no other way...

If someone have data for the Norma and Vihtavouri powders I would appreciate?
I also read about duplex loads with the Somchem S335 and S365, where put 50% of each in the load, first the S335 and then the S365? I am a bit scared for this practice!! But both these powders on there own do not give me the performance that I need for the Brenneke! Cannot get over 2400f/s without pressure signs...
If I can just get over 2500f/s, then I would be happy!
