Polymer Coating
Polymer Coating is a modern, high-tech coating that is chemically bonded to the surface of the bullet. It requires no additional lubricant and will not foul the bore if used correctly – even at modestly elevated pressures where a traditionally lubricated bullet would start to show signs of leading the barrel.
All of our polymer coated bullets come in a black/gold finish. The specific final colour may vary slightly from batch to batch due to the manufacturing process and does not affect the performance of the bullets in any way.
Loading Information
We do not supply load data for any of our bullets. Please consult a loading manual prior to hand-loading any bullets and ALWAYS follow safe load development practices. Failure to follow safe loading practices may result in injury or death.
To get the best possible results from our polymer coated bullets, it is strongly recommended that you apply only the smallest amount of crimp appropriate to retain the bullet in the case. Over-crimping the case mouth may scrape the coating from the bullet as it is fired, resulting in excessive leading of the barrel and poor accuracy. For firearms with tube-fed magazines, your crimp should be strong enough to resist the bullet being pushed further into the case by the magazine spring.
For revolvers, the crimp need only be strong enough to withstand the recoil pulling the bullet from the case mouth. If your load requires a strong crimp to develop a high internal case pressure before the bullet moves, check your bore for signs of leading.
It might be necessary for you to use a traditionally lubed bullet instead if you see signs of lead fouling.
Hardness
All of our lead products are cast using our own lead alloy, developed in-house. All of the bullets cast from this alloy have a Brinnell Hardness (BHN) of 12-14.
How hard is hard enough? When Elmer Keith was busy inventing the .44 Magnum he settled on an “ideal” hardness of around 11BHN, achieved with a lead/tin alloy of 94%Pb and 6% Sn. He considered these bullets to be hard enough for a muzzle velocity of 1200fps with a 240-grain “Keith” bullet.
Today, hardness values of 18+ are not uncommon and what is considered hard today is not the same as what the people who invented the calibres we shoot today would have thought! Our opinion is that for most pistol-calibre applications you simply do not need a bullet that hard to be effective. In almost all cases it is more important to have a correctly sized bullet with the right powder load than a harder alloy.
