Why Hunters & Shooters Choose CCI Maxi-Mag

This design ensures deep penetration, making it effective for humane kills on small to medium-sized game, including animals up to the size of a coyote. Additionally, the controlled expansion helps minimize pelt damage, offering an advantage over lighter, more frangible varmint loads for hunters who value clean, ethical harvests.

Its aerodynamic design ensures stability in crosswinds, with minimal drift even in 10–15 MPH wind conditions. Additionally, it maintains a consistent velocity with a tight ±15 FPS variance, providing dependable accuracy shot after shot, whether in the field or at the range.
