When using T/C molds, follow the instructions supplied with the mold block. Lead is a potent, systemic poison that serves no known useful function once absorbed by your body. Lead can be absorbed into your body by inhalation (breathing) and ingestion (eating). Taken in large enough doses, lead can kill you in a matter of days. Even in small quantities, lead dust, fumes or mist can be inhaled or ingested and cause serious injury in the respiratory system. Children are especially vulnerable to this.
Never allow children to be present in the room where you are casting bullets. Ensure that your work area is well ventilated so that hazardous vapors are ported away from you.
Lead can also be absorbed through your digestive system if lead gets in your mouth and is swallowed. If you handle food, cigarettes, chewing tobacco, or make-up which have lead on them, or handle them with hands contaminated with lead, this will contribute to ingestion. Always be sure to wash your hands after handling lead.
No eating, drinking or smoking should take place in any area you are working with lead.
When casting lead bullets, use only pure lead (PB). Wear long sleeves, safety glasses, gloves, and a canvas apron to protect you against lead splatters. Molten lead will react violently if it comes into contact with water or other liquids. The molten lead can erupt, with steam and hot lead spewing in all directions. Keep your bullet casting furnace away from possible sources of water such as the condensation from overhead pipes. Be certain that any new lead being added to the old lead is absolutely dry.
FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN INJURY AND/OR DEATH TO THE BULLET CASTER OR BYSTANDER, AND DAMAGE TO PROPERTY.
Muzzleloading projectiles must be cast from pure lead. Most lead alloys commonly found in Linotype and wheel weights contain antimony. While such alloys are very desirable for fixed cartridge projectiles, they are impractical for muzzleloading use. Alloys containing antimony are harder and lighter than pure lead. Consequently projectiles cast from such materials will be overly hard (depending on the amount of antimony present) and somewhat lighter than the bullet weight listed for the mold. The biggest problem, however, is that antimony alloys have less a shrinkage factor than pure lead. Antimony alloys produce an extremely hard, over size projectile which is very difficult to load properly. Pure lead can be obtained from a plumbing supply house.\
This booklet and the Thompson/Center Catalog lists a series of round ball, Maxi-Ball and Maxi-Hunter molds that are proper for use with our firearms. All T/C bore diameters, patch thickness and mold dimensions are carefully calculated to produce a safe result when used with our recommended Black Powder charges and a pure lead projectile in the appropriate caliber.
The reader must realize that Thompson/Center has no control over cast projectiles, bullet molds or patch material offered by other sources. Before using such items, the user must assure himself that the components or molds are proper and safe to use with our firearms. If you have questions concerning the correctness of a product or component, write to the Customer Service Department, Thompson/Center Arms, P.O. Box 5002, Rochester, New Hampshire 03866.
