I recectly saw an ad online for a J.P. Sauer hammer drilling that was supposed to have a 9.3x74 rifle barrel. When I asked if the seller meant a 9.3x72 which would have been more likely he stated it was a 9.3x74 meant for black powder. I thought the 9.3x74 came out in the early 1900's as a smokeless caliber. Any body hear of an early low pressure load? Wish I could buy the drilling since I already load for the Ruger No.1 in that caliber. The seller said it was sold to him as a 9.3x72 but it slugged .366 and you could camber a 9.3x74.
