Looking for Data for 280 Ack Imp for RL-26

[6.5_sWv]

Im looking for a starting point to use Reloader 26 in my 280 Ackley Improved with the Sierra 165gr GameChanger. I have several loading manuals that have data for the the 280 AI but none of them have Reloader 26 listed. I emailed Sierra and they didnt bother to reply. Could someone run this bullet/powder combo in Quickload possibly ? My rifle is a Kimber 84L with a 24'' barrel. Will be using Federal 210GM primers and Remington once fired 280 brass that was fire formed in this rifle.

Thanks
Ben

With 160 Accubonds, my max load of RL 26 is 59.5 grains...

With 168 AccuBond LR bullets, its 58.5 grains.

So I'd say 56 grains would give you a safe start.
