[QUOTE="EXPRESS, post: 1226809, member: 1441"] AZ, this is a .338 Winchester mag, not a Lapua, on the Hodgdon site the highest max velocity I could find was 2440fps for the Win mag. I am getting 2485 with a very mild load, and reaching 2620 with the maximum published load of 72 grains of VVN560. As I've said, there are no other factors I can think of that could influence the pressure/velocity. Air temperature was 26°C while shooting, the ammo and rile had been sat in the shade in a cool spot for several hours before I shot. I like to put my gear out (I shoot from home) and let it settle to ambient temperature in the shade for my records. This afternoon I will be pulling the rifle and ammo out of the freezer (I have a big freezer) and testing it at -20 and 0°C to see what results I get to determine temperature sensitivity. [/QUOTE]
