THat load should get you either side of 2750 from a 26" Maybe 2775. at altitudes of 4000 to 5000 ft. Unless you use some of the chrono's that some members on here own.
I would shoot that load at 300 yards and see what ya get there. In terms of MOA my 338 LM with 300 Bergers shoots tighter and more consistant at longer distances than 100 yards.
I have no use for a light bullet in a .338 so I can't help you wth the last question.
