RE: .280 loads for elk?
58.5 grains of IMR7828 (Nosler Manual)..Remington Case Federal 210 primer 160 grain partition .020 off the lands. I get 2850average chronographed out of this combo and it is OK for Elk. Work up this load carefully in your rifle. Pretty limited offerings as far as loaded ammo goes so shoot for premium bullets first..if you can't find some then use Hornady as a last resort.
