Think of your 19" barreled 280 Remington as a 7-08. Don't worry about the speed, there's a lot of 7-08 shooters killing deer and elk at 400-500 yards with the right bullet in the right spot.

I think Grand would be too slow for optimum results, especially with the shorter barrel.
Someone mentioned IMR4064 and that might not be a bad choice in a 19" barrel.

FWIW, I get discoloration when I aneal my brass. When I clean the brass in the Frankfort Arsenal wet tumbler, they come out clean and look like new brass.

My wife has a M48 Mountain Carbon in 30 Nosler. She has the Nosler brake which takes it down but even without the brake the recoil isn't that bad. She's running 180 gr BT/AB's at 3100 fps.

These guys have been to our hunting show the past couple of years. They seem to draw a crowd.
If I lived and hunted in the shotgun/restricted rifle zone, I would definitely taking a closer look at their loadings.

I'm using 81.0 grs of CFE223 with the 250 gr TTSX and 250 gr SGK. Its an upper end load.
I've also had great results with StaBall 6.5 with the 260 gr E-Tip.
