How to Avoid Misfires with .22 LR Rimfire Ammunition

“22 Plinkster” is an avid shooter who has produced a number of entertaining videos for his YouTube Channel. In the video below, he tackles the question “Why Do Misfires Occur in .22 LR Rimfire Ammunition?” This is the most common question posed to 22 Plinkster by his many viewers. He identifies four main issues that can cause .22 LR misfires or faulty ignition:

1. Damaged Firing Pin — The dry firing process can actually blunt or shorten the firing pin, particularly with older rimfire firearms. Use of snap caps is recommended.

2. Poor Ammunition — Some cheap brands have poor quality control. 22 Plinkster recommends using ammo from a manufacturer with high quality control standards, such as CCI and Federal.

3. Age of Ammunition — Rimfire ammo can function well for a decade or more. However the “shelf life” of rimfire ammunition is not infinite. You ammo’s “lifespan” will be shortened by heat, moisture, and humidity. You should store your rimfire ammo in a cool, dry place.

4. Mishandling of Ammunition — Tossing around ammunition can cause problems. Rough handling can cause the priming compound to be dislodged from the rim. This causes misfires.

Preventing misfires is essential if you want to succeed in NRL22 competition and other rimfire competition disciplines run “on the clock”.

Mystery Malfunction and Then Kaboom! What is Your Call?

AR kaboom detonation over charge ammo 3-Gun

What happens when a round goes off unsafely in an AR? Watch this video and see. At about the 00:40 time-mark the shooter has a malfunction (click no bang), with a round. He then removes the magazine, and clears the chamber (we think). On the next round, at 00:53 you hear a “Bang” and see a big puff of smoke coming out of the upper receiver (see photo at right). This has been called a “detonation” by the video-maker, but we’re not 100% sure what happened. What do you guys think? Watch the video carefully, and state your conclusions in the comment section if you wish.

What Caused this Malfunction? Watch Video…

In any event, the shooter is fortunate his upper did not completely fracture, launching shrapnel into his face or other body parts. This could have turned out much worse. Here are screen-shots from the video, showing details of the gun after the accident, along with the recovered brass case, which separated near the case-head.
