For ultimate consistency and accuracy, many seasoned hunters turn to Speer Hot Cor Rifle Bullets. These bullets are manufactured using a special Hot Cor process in which molten lead is poured directly into the jacket. Because of this, the bullet is more consistent and available in a wider range of calibers. Speer bullets made using the Hot Cor process include 6mm, 6.5mm, 7mm, 7.62mm, 8mm, and 9.3mm, as well as .25, .30, .32, .35, .45, .270, .303, .338, .375, and .416 calibers. These bullets are also precision-made in several different diameters and grains, according to the exact need.
