RE: 7x64 questions...
Colorado Elk -
The Lee #2 Manual has a good bit of info for loads for the 7x64. About 4 1/2 pages worth. There are loads listed for 150, 155, and 160 grain bullets, but not for 156. They also have the main brands listed to load, including IMR, A-XMR, Hogdon, and VV. Let me know if any of these will work for you, or you can pick up the book for about $20, a decent investment IMO. Good luck
