Has anyone loaded this cartridge in a pistol length barrel? I have a 15" barrel and will use the 120gr. & 140gr. bullets for target, silhouette and hunting. I have loaded the 6.5 Creedmoor in a rifle with a 26" barrel and wonder if the same powders in the Hornady manual, or others would be better suited to get about 2,200-2,300 fps with those bullet weights. I don't need maximum speed for target and silhouette work. Thank you.
