2. Inspect the brass
The brass casing is what holds the primer, powder, and bullet together. It’s also what’s extracted from the gun after the round is fired. So, it stands to reason that if the brass is in good condition, the rest of the cartridge is likely in good condition as well.
When inspecting brass casings, look for any sign of corrosion or pitting. These are sure signs that the ammo is no longer good. Also, make sure the brass is not dented or damaged in any way. A small dent may not seem like a big deal, but it can cause the bullet to veer off course when fired.
3. Check the primer
The primer is responsible for igniting the gunpowder. It’s a small cup of lead styphnate that’s located in the back of the brass casing. When you strike the primer with a firing pin, it causes a small explosion that ignites the powder.
To check the primer, simply look at it through the opening at the back of the brass casing. It should be flat and seated properly. If it’s not, the ammunition is no longer good.
4. Look for signs of moisture
One of the biggest enemies of ammunition is moisture. Water can cause all sorts of problems, such as corrosion and rust. It can also cause the gunpowder to clump together, which will affect the accuracy and power of the round.
When inspecting your ammunition for signs of moisture, pay close attention to the brass casing and the powder. If either one appears wet or damp, it’s best to err on the side of caution and dispose of the rounds.
