280 AI - Anyone have experience with reloads

Brian,

I have done a lot of shooting and hunting with a Ruger Model 77 rechambered to 280 Ackley. My best hunting loads have been with 150 and 160 gr partitions at around 3000 fps using H4831 or H 450 out of the 22" Ruger factory barrel.

My current 280 AI, another Ruger 77, has a 25" Shilen barrel and gets about 100 fps more with the same powders, 150 fps more using RE22.

The loads give good case life, no expanded primer pockets with repeated reloadings in R-P brass
