Techna Clip highlights the most common reloading mistakes and hazards below.
- Cracked Cases – Small cracks around the base, shoulder or neck of the cartridge case are barely noticeable. Usually they simply let gasses escape, but sometimes they can crack into the shooter’s face when fired. Before shooters reload, they should carefully look over each casing, examining it carefully for any signs of cracks. Bright rings that appear around the base can also indicate a potential separation or damage.
- Dented Cases – Sometimes the sizing lube can cause excessive divots in the case, which is most common with bottlenecked rifles. Those with holes have limited efficiency and excess lube can build up in the die or case shoulder area. Firing dented cases can not only decrease capacity, but also it can also boost pressure, which leads to splitting and cracking.
- Excessive Powder Charge – Handgun cartridges can easily double charges. Before seating bullets, use a flashlight to scan for powder levels that may appear low or high. If loading using a progressive press, consider purchasing a powder level check system. Never install the incorrect powder types.
- Inadequate Primer Seating – Primers that do not have full seating can lock up actions, which are especially sensitive in semiautomatic firearms. All primer pockets need to remain clean of buildup to help them maintain proper functioning. No loose powder particles or other debris should be loose, as this can affect the weapon’s accuracy.
- Too Much Primer Seating – Primers should be seated below the surface of the case head. Shooters should develop a feeling for properly seating primers without crushing them, which is dangerous.
- Untrimmed Cases – Semiautomatics are easily hindered by cases that feature excessive lengths. It is important to always trim cases appropriately and according to specifications.
- Bullets Seated Too Far – Many long-range rifles may shoot soft, match-type bullets. Unfortunately, when removing these from the chamber, there is a risk that they may be difficult to remove, which can cause powder spillage.
- Bullets Shaved by Case Mouths – When purchasing a new weapon, always make sure to chamfer the inside of the gun with a low-drag case to help avoid any potential accuracy issues.
- Crimping – Crimps help secure bullets against unwanted movement, but excessive crimping in handguns can cause failed cartridges in the chamber. Forgo distorting the case neck and never squeeze bullets out of shape.
- Inadequate Crimping – If bullets are not correctly crimped, they can pop down into the cartridge case, or even protrude out of the chambers’ mouth.
