Hey guys,

I am currently building a 6.5X280 AI and I am looking for load data. I am considering starting with IMR-4831/H-4831, and I will most likely be shooting either a Berger VLD 140, ELD-X 143, or an ELD-M 147. Any information helps whether it's with 4831 or any of the listed bullets or not. Thank you!
 
look at the sherman loading data for the 6.5 sherman and start with a few grains less and work up you can also find some 6.5-06 AI load data just use the search up at the top right of the screen I run rl-23 in mine
 
Friend has built a lot of 6.5-280AI s, most likely 15-20, and they ve run H1000 for years. R26, 7828, etc will all give good performance also. I think the 4831 s would also be good; might give up a little velocity to the slower burners though.

Thanks, anyway you could put me in contact with him?
 
You don't have PM capability yet.. are you wanting load data, velocities or what? I can get data from him if that's your intent.
 
Loading 58-59 grs with 150 MK. Said 58 is better on the brass. Might get a grain more with the 143 bullet. I d work up as it s a stout load. 2900-2950 ish depending on barrel.

R26 has shown promise too but at a couple grs less, he didn't have that load data handy. Good luck
