The Speer Hot-Cor Rifle Bullet 303/7mm .311-inch 150 gr Soft Point (Speer part no. 2217) is built using Speer’s Hot-Cor process, in which molten lead is poured directly into the jacket rather than pressed in as a separate step. That process makes the finished bullet more consistent from core to core, and it’s why Speer offers Hot-Cor construction across such a wide range of calibers, diameters, and weights. Seasoned hunters who want dependable accuracy from handloaded rifle ammunition often turn to Hot-Cor bullets for exactly that consistency.
