Description
350 Legend subsonic ammo from Winchester Super Suppressed gives rifle shooters a 255-grain Open Tip Range load in a 200-round case. Each SUP350 round uses a 255-grain OT bullet with new Boxer-primed brass casing and Winchester’s subsonic Super Suppressed design.
Winchester builds this load for reduced noise, reduced recoil, and decreased barrel or suppressor fouling when used in compatible firearms. Current product-spec listings show 1,060 fps muzzle velocity with 636 ft-lbs of muzzle energy, keeping the load below the speed of sound for subsonic range use.
Each case includes 10 boxes of 20 rounds, making it useful for range sessions, function testing, and keeping one consistent suppressed-shooting load on hand. The Open Tip Range bullet is made for target and range shooting through suppressed and non-suppressed firearms.
Compared with standard supersonic 350 Legend hunting loads, this Winchester SUP350 option is better suited for quiet range work and suppressor-focused practice. For related options, browse 350 Legend Ammo, Bulk Rifle Ammo, and Winchester Ammunition.
