I got the 9.5X57MS cases from Buffalo arms & are RP 35 Whelen reformed cases. I am loading 270 gr Hornadys with 47 gr & 48 gr of AR 2208 (Varget) and & 250 gr Sierras with 50gr & 51 gr of the same. I might try AR2206 (similar to IMR 3031) if the velocity is too low with AR2208. Original ammo is almost impossible to get. I have 2 rounds of Kynoch & another 27 to get from the previous owner. Those will most likely stay as a collection. I am not sure if it is worth shooting the stuff that could be 50 years old or older.

Does anyone know of 9.5 head stamped cases at reasonable price? I see Horneber cases are available but quite expensive.
