I have developed a subsonic load for the 270 Winchester shooting the 140 grain Berger VLD hunting bullets. It runs 1020 fps in a 22″ barrel unsuppressed, and 1060 fps suppressed.These also make great plinking rounds. They are a little louder than a 22 LR with no suppressor, and super quiet with a suppressor. If you are sighted in at 100 yards with full power 130 or 140 grain ammo, these subsonic rounds will impact about 9″ to 15″ low at 100 yards. Priced per 100 rounds. New Nosler brass, Berger 140 grain VLD Hunting bullet, and Federal 210 primer.
