for those who want a 9.3 x 64, but not the hassle of getting brass, might consider this. the 338 win mag case is just like a belted 9.3x64. the 338 would neck up easily for a ready supply of brass. you now have a belted ballistic twin. if having a reamer made, one consideration might be the throat angle. the 9.3x64 has a much lower angle than the now commonly used 1 degree30 min. this lower angle definitely affects pressure. my choice would be to go with the lower angle. bruce.
