*The SAAMI maximum COAL for this cartridge is 2.800”. Loading the 225-grain TSX to this COAL places the case mouth in front of the junction between ogive and shank. If your magazine is long enough to accommodate it, seat to a longer COAL of 2.895” and crimp the case mouth into the front cannelure groove. If your magazine box limits you to using 2.800”-inch-long cartridges, use a factory crimp die to crimp the case mouth tightly against the bullet to improve feeding. Beware of bullet setback in the magazine under recoil. If the bullet does set back in the case, do not fire the round. Barnes recommends using the 200-grain TSX in .350 Remington Magnum rifles with short magazine boxes.
Barrel: 20" with 1:16" twist.
