I don't know what you are seeing for ES, but remember that Chronographs can be fincky and fib to ya. Your load is in the ball park of max. Most .338 edges I have worked with will see pressure at 92.5 or 93 grains with 300's. These loads have proved to make for short brass life with the rifles I worked with using RP brass.

How about this? Take your rifle out and shoot a few 3 shot groups at 800 or 1000 yards with this new load you have. Then measure your actual verticle spread. Tape measures don't lie.
