280 AI Load Data

Good day all I just recently purchased a Kimber Montana in a 280 AI, I had some slight mods done , trigger, bedding re-crown, now I am after some good load data , I was thinking of using some 162 AMAX or 140 AB ,or some 154 SST I also have , so if any of you Montana guys have any load data to share that would be greatly appreciated, I am hoping this gun will shoot .75-.5 MOA .

Not from Montana. But I think I can help a bit.
I've got a couple custom .280ai. Both of my rifles like H4831. Ive tried faster and slower burn rates and find 4831 to be the best for my rifles. With 162g maxes and 160g abonds over 59.3g of H4831 I'm getting reliable 1/3 Moa accuracy.
Hope this gets ya started.

+1 either H or IMR 4831 is a great powder for both the .280 and .280 Ackley. Its also one of the best .270 WIN propellants.

How long is your barrel? Retumbo seems to slow.

Well that 26" is nice to have, especially when shooting those slower powders.
