I think that is excellent. A 285 at creedmoor speeds. I'm riding your data coat tails. My 338 is a work in progress.Played around with H-1000 and the 285 Hammer.
Didn't really have any solid data to go off of, but I know many people top out with the 300's around 88-89 grains, so I figured that this being a 284, and that generally Hammer bullets use the same or a little more powder than lead core bullets of the same weight to reach pressure, I would work from 87 to 80 in .5 grain increments, performance was as follows in these photos:

These were seated .020" off the lands, which gave an OAL of 2.833", these suckers are long ha ha. Seems like the bese accuracy seems to be high 2700's, but it's obvious there is a velocity node around 2730-2740, usually the accuracy falls in there, but not this time.
Overall pretty happy, what are y'alls thoughts of 2780 with a 285 in a 24" with H1000?
