Q: I’ve just had my Ruger M77 in .280 Remington rechambered to the Ackley Improved version and have fireformed 100 rounds of factory ammo without losing a single case. That’s darned impressive. Now I’m ready to start reloading and am looking for two or three good loads, Can you suggest a recipe for each of the following bullets – Hornady 140gn GMX, Barnes 150gn TTSX and Nosler 160gn AccuBond? The powders I have are AR2213sc, Reloder 19 and 22. Should I use standard or magnum primers?
A: I’m very impressed with the .280 Ackley Improved which treads closely on the heels of the 7mm Rem. Mag., but has less
muzzle blast and recoil. The Hornady 140gn GMX gets scooted along at 3195 fps by 63gn of Re-22; the Barnes 150gn TTSX and 59gn of RE- 19 gets a solid 3065 fps; and the Nosler 160gn AccuBond and 59gn of Re-19 churns up 2990fps. If you want a good varmint/predator load try the Barnes 120gn TTSX and 64gn of AR2213sc for 3360fps. The .280 AI gives magnum performance in a standard rimless case and I’d rate it as Ackley’s finest wildcat.
