Winchester's Big Bore 10mm delivers 200-grain semi-jacketed hollow points at 1175 fps. Controlled expansion makes this round dependable for personal defense and hunting applications.
Winchester Big Bore ammunition represents a thoughtful approach to 10mm ballistics, combining proven bullet design with reliable performance across multiple applications.
The semi-jacketed hollow point design is engineered to balance two critical requirements: controlled expansion and reliable penetration. This approach ensures the bullet performs predictably in both personal defense and hunting scenarios.
Expansion Control: The SJHP design delays expansion, preventing over-expansion that would limit penetration while still delivering the stopping power hollow points are known for.
Dependable Performance: Winchester's manufacturing standards ensure consistent velocity and reliable feeding across a wide range of 10mm firearms.
This ammunition represents Winchester's commitment to delivering practical, field-proven solutions for serious shooters.
