Hi Kirby,
Can you share the load you are using for the 140 gr AB in the 280 AI?
I have 280 AI on a M700 action that has been blueprinted and a Hart 24" #5 flutted barrel. I have found my load with the 160 gr AB and 62.0 grs of RL22. It shoots in the .2's at 100 yds if I do my part. As for the 140 gr AB's, 64.0 grs of RL22 is shooting in the .5-.6" area, not bad BUT I am trying to find a load that will shoot similar to the 160 gr AB. I am planning on using the 160 gr AB for WT Deer unless I "find" the right load for the 140 gr AB's.
I hope that no one feels that I am hijacking the thread, I think that the 140 gr AB would be excellent for WT Deer.
Regards,
