Made with a variety of materials like precision made cold swagged cases Lead Bullets and copper plated lead bullets you will see a difference but most of all you will feel the difference of accuracy and impact of these classic reloading bullets.One of the most interesting is that Hornady Lead Frontier Pistol Bullets come in a size that is much smaller than a wildcat .45 caliber. When used in a 45 caliber chambered in .454 cal it is possible for the bullet to be captured by the cylinder pin and fire through the sleeve of a 45 caliber reloadable bullet and the fire will continue to function until the bolt is released to release the round. This is mostly due to the design of the Round Ball Pistol Frontier Lead Bullet which features a flint base design in perfect symmetry with the base of the bullet. The flint minimizes leading because the roughened out area under the bearing surface holds the wax from the lubricant from a gunpowder and distributes it evenly over the bullet. Once the round is released from the barrel the wax acts like a seal preventing the bullet from slipping as the round travels through the bore. Hornady Frontier Lead Pistol Bullets are built to exacting standards of quality. Each bullet is knurled and greased before being packaged so that the lubrication can be spread evenly over the entire bearing surface.
