Maxim Defense 5.56 NATO 70gr TUI Ammo

The Maxim Defense 5.56 NATO 70gr TUI load (Maxim part no. MXM49002) uses a tumble-on-impact terminal mechanism rather than a traditional expanding hollow point. Instead of mushrooming outward, the solid, lightweight 70-grain bullet is built to destabilize and tumble through tissue after impact, creating a wide, irregular wound path while resisting the over-penetration that can affect standard ball ammunition. That makes it a purpose-built option among rifle ammunition for AR-15 shooters who want a different terminal mechanism than a conventional soft point or hollow point.
