Missouri Bullet Company bullets are hardness optimized and coated to reduce the amount of lead left in the barrel so you can spend more time shooting and less time cleaning your guns. An optimally hard lead bullet is simply one which obturates at a given pressure sufficiently to seal the bore against the gases which would otherwise “cut through” the soft lead (called “gas-cutting”, forcing molten lead into your rifling.  A bullet which is too hard won’t obturate and seal the bore, because the gas pressure is insufficient to expand the base of the bullet.  A bullet which is too soft at a given pressure will experience excessive base expansion and vaporization of the lead, causing leading.

Missouri Bullet Company optimizes

The Missouri Bullet Company optimizes bullets for your intended application.  They don’t take a “one size fits all” approach to manufacturing your bullets.  MBC works with certified analysis foundry alloy in two hardnesses in order to provide you with the bullet hardness that works best for you. One is 2% tin, 6% antimony, balance lead for harder bullets at 18 BHN and the other is 1.3% tin, 4% antimony, balance lead for bullets optimized for lower velocities at 12 BNH. While it is expensive to maintain a dual supply of alloy, the payoff is in the fact that you have a choice of bullet hardness suited for your particular application.

Hi-Tek coating

The Missouri Bullet Company also utilizes a Hi-Tek coating on bullets to eliminate the need for messy lubes while loading ammo.

Specifications

Many indoor ranges prohibit the use of lead bullets but allow the use of coated bullets due to the fact that no lead is exposed to the environment. Leading of the bore is dramatically reduced, as is lube smoke. Long shooting sessions do not have to be interrupted by bore cleaning. Higher velocities can be attained with Hi-Tek coated bullets. There are also associated health benefits for the reloader, as there is no touching of bare lead. Hi-Tek also reduces the force required to seat and crimp because the bullets are slippery. The bullets actually look “wet” and are very slippery. This lubricity reduces friction-related heat as the bullet traverses the bore. In summary, Hi-Tek coated bullets offer the advantages associated with plated bullets without the expense.
