I'm having a mountain rifle built for deer hunting at medium and long range. No muzzle brake. I'm leaning heavily toward a 280 Ackley Improved with a 26 inch barrel, and using the Nosler Custom brass. Anyone willing to share their favorite load data and results with this cartridge? Until the LRs become available, I'll likely load the regular 160 gr accubonds. Is 3,000 fps too much to expect?
