[QUOTE="azsugarbear, post: 3074991, member: 4809"] My 270 Allen Mag was the most overbore rifle I have owned. The cartridge was an improved 338 Lapua case necked down in several stages to a .277. The rifle wore a slow twist, 26" barrel that shot the matrix 195 gr. bullet. I no longer have my reloading notes, but the powder charge was close to 100+ grains of the slowest burning ball powder i could find (the stick, or kernel powders would bridge up in the shoulder/neck area and cause dangerous spiking pressures).
