The Hornady XTP 9mm Bullets, 124 gr Hollow Point (Hornady part no. 35571) are Hornady‘s best-known handgun bullet, sized at .355 in. diameter and sold 100 to a box. Precise serrations divide the XTP into symmetrical sections, and Hornady varies the jacket thickness down the bullet’s length so expansion is controlled rather than erratic. Total uniformity of core density ensures balanced expansion as well as in-flight stability, and this 124-grain weight carries a .165 ballistic coefficient and .141 sectional density. XTP is designed for hunting, self-defense, and law enforcement applications, and it’s a favorite of competitive shooters as well.
