I have a Remington 280 AI that was barreled by Kenny Jarrett. I am trying 140 grain Accubonds and cannot come up with a load that seems to be the ''cat's meow''. Any help on your pet loads would be appreciated.
I shoot the standard 280 with 140's and 57 grains of H-4831 although it is not the AI version H-4831 or RL-22 should work well for you pick a mid range load with either powder for the standard 280 and work up and you shouil be able to find something good with a bit of effort.
The following load has been exellent in my .280AI average .35" at 100yds and 1.5" at 600yds in good conditions. gives a MV. of 3125fps from 24" barrel
