here is the load data that berger sent me for the .280 my best results for accuracy has been 58.5 grains of IMR7828 ssc. Do not use I repeat DO NOT USE h-414 I tried it cause I had some laying around and it even though it says it fills the case to 87% it sure doesn't look like it and I had a few that the trigger would go off then a split second later the gun would go off I'm guessing because the powder was all in the front of the case. But here ya go.

I run 57 grain's of H-4831 under the 140 ab and 58 under the 140 berger. The accubond load was easy to come up with and accurate from the get go. The berger load was a bit more work finding the right jump but is just as accurate as the ab load and shoots flatter.
