I did find 7.5x54 mas and the Swiss cartridge in the Hornady number 6 manual.


For 150's in the mas;

IMR 4895; start 35.2 for 2200fps, max 42.1 at 2500fps

IMR 4064; start 38.1 for 2200fps, max 44.4 at 2600fps, which by the way was the best velocity of all powders in their chart. (tied with Viht n160)

FWIW I shoot 155's in my swiss k31 with IMR4064 and it works well.
