My first post......
I have an .270 ackley with 25" douglass air gauged stainless barrel. What ive learned its all about powder selection like with any other caliber. nosler 140 accubond, imr 4831, fed 215, norma case gives me 3100 fps easily without pressure 10 ft from muzzle. Standard 270 fireform load was 2800 fps. I started out with some other slower powders and was disappointed with the performance.
