The Win Bioammo 12ga 2.75" #4 25/250 - WNBLS3040 is Winchester's premium shotgun ammunition engineered for hunters and sport shooters who demand reliable, consistent performance in the field. Designed as a 25-round box of Winchester's trusted Bioammo line, this 12-gauge load delivers the downrange energy and pattern density required for upland game hunting, clay shooting, and general sport applications. Winchester's Bioammo designation indicates ammunition formulated with advanced ballistic design to maximize effectiveness while maintaining shooter control and accuracy across varied shooting conditions.
The #4 shot size in this 2.75-inch shell provides the optimal balance between pattern density and individual pellet energy for medium-range shotgun work, typically effective to 35–40 yards depending on choke and shooter skill. Winchester manufactures this ammunition using quality primers, consistent powder charges, and uniform pellet sizing to ensure shot-to-shot reliability and predictable patterns. The 2.75-inch standard hull dimensions fit any 12-gauge chamber rated for 2.75-inch or longer shells, making this load compatible with the vast majority of modern and vintage 12-gauge shotguns, including semi-autos, pumps, and over-unders.
Shooters who regularly pursue upland game, participate in sporting clays competitions, or practice defensive shooting will appreciate Winchester's reputation for quality control and performance consistency. The 25-round box format offers convenient carrying and counting for range sessions, competitions, or hunting trips where reliability and predictable ballistics are non-negotiable. Whether you're breaking clay targets or pursuing game birds, the Win Bioammo 12ga 2.75" #4 ammunition delivers the proven Winchester performance that professionals and serious shooters trust.
