BASE GUARD™ BULLETS
Base Guard is a trade-marked name for Corbin Manufacturing's fouling-scraper disks attached to the bottom of the bullet at the same moment the bullet is formed. These disks form a sharp burnishing tool edge, which scrapes fouling out of the bore with every shot. The disk rotates with the rifling, regardless of whether the body of the bullet skids or fails to turn in the rifling, and thus seals the bore against powder gas (unlike a gas check, which is crimped on the surface of the bullet and cannot turn separately from it while in the bore).
Base Guard advantages are: a high degree of accuracy, automatic cleaning of powder and lead fouling from the bore, and elimination of traditional lubrication even with velocities as high as 1,400 feet per second, in most guns. However, they do not work in all bores because if the bore has exceptional roughness, a swelling or uneven diameter, the gas will escape around the disk and cause gas cutting of the bullet, and the bullet lead will seep past the disk at any point where there is not a perfect seal between disk and bore.

Casting compared to swaging.
Casting uses molten lead, pouring it directly into a mould. Swaging uses room temperature lead, from a spool of wire or a pre-cast cylinder (core) made to fit into the swage die easily Hot lead expands the mould, changing its size. For example, a .0015 inch diameter control is considered rather good for cast bullets before sizing. Swaging dies remain at room temperature. They operate using pressure to flow the lead. Basic physics indicates that the diameter control over bullets made this way, by swaging, just has to be more consistent than casting allows. For example, a .0001 inch diameter control is considered the upper acceptable limit for a swage die, which is more than 10 times better than the best cast tolerance.
Casting is done in a split mould, which swings open and closed on every cast, wearing the pivot pin, and exposing each half of the mould face to cool room air while the hot lead bullet retains heat on the other side. Swaging is done in a solid die with a diamond-lapped hole, pressing material under tons of pressure and ejecting it back out the same end givng us the capability of delivering .5% weight accuracy versus the 1% standard.
