Custom-made gas-checked bullets can be sized to fit the bore of a gun or rifle. This will give the rifle greater accuracy because the gas-checked bullets are pushed out of the barrel at a higher velocity without leaving any deposits to foul up the barrel.

Difficulty: Moderately Easy
Instructions
  1. Step 1

    Understand the need for gas-checked bullets. The high pressure of guns and rifles with maximum loadings lets the gas that propels the bullet escape during firing. Lead will deposit inside the barrel, which will unbalance the bullet. A thin layer of slightly harder metal at the bullet's end seals the propellant gas from leaking.

  2. Step 2

    Know which guns work best with gas-checked bullets. The most common types of guns that use gas-checked bullets are .44 Magnums and .357 Magnums. There are also a few old military rifles like the .303 British or 7.62 by 54 R.

  3. Step 3

    Identify a gas-checked bullet. Gas-checked bullets must be designed for that special use. Look for a thin cup at the bottom of the bullet. It will be made of brass, zinc, aluminum or copper. This protects the bullet from getting melted by the heated gas and deforming to throw the bullet off balance. The non- gas-checked bullet will be a solid color without any cup on the base.

  4. Step 4

    Load the gas-checked bullet with your fingers the same way you do a non-gas-checked bullet. Gas-checked bullets tend to be a little slippery. If it doesn't go in straight, tap the bullet's nose with a rubber hammer and attempt to seat it again.
