Can You Shoot .22 Shorts Out of a .22 LR? The Short and Long of It
The simple answer is: generally no, you should not shoot .22 Short cartridges in a firearm chambered for .22 Long Rifle (LR). While they might seem similar, the critical differences in cartridge dimensions can lead to serious consequences.
This article will delve into the specifics of why this is dangerous, exploring the subtle yet significant differences between .22 Short and .22 Long Rifle ammunition and the potential risks associated with mismatched ammunition and firearms.
Understanding the Cartridge Differences
The names themselves hint at the key distinction: length. A .22 Short cartridge is, as the name implies, shorter than a .22 Long Rifle cartridge. This seemingly minor difference translates to a critical variation in the positioning of the bullet and propellant within the firearm's chamber.
-
.22 Short: This cartridge features a shorter case, holding less gunpowder and a lighter bullet.
-
.22 Long Rifle: This cartridge is longer, containing more gunpowder and usually a heavier bullet. The extra length allows for significantly higher velocity and energy upon firing.
The Dangers of Mismatched Ammunition
Shooting a .22 Short in a .22 LR firearm creates several potential hazards:
-
Chambering Issues: The shorter .22 Short cartridge may not fully seat (become properly positioned) in the .22 LR chamber. This can lead to a dangerous misfire, potentially causing the firearm to malfunction or jam.
-
Bullet Obstruction: Even if the .22 Short chambers, the shorter case may leave insufficient space for the bullet to properly engage with the rifling (the spiral grooves inside the barrel). This can lead to inaccurate shots, dangerous ricochets, or even a barrel obstruction.
-
Increased Pressure: The .22 LR chamber is designed for the higher pressure generated by a .22 LR cartridge. Firing a .22 Short could cause unexpectedly high pressure in the chamber, potentially leading to damage to the firearm, injury to the shooter, or even catastrophic failure.
What About .22 Long?
The .22 Long cartridge, while longer than the .22 Short, also generally shouldn't be fired from a .22 LR firearm. While less risky than firing a .22 Short, the potential for improper chambering and pressure issues still exists.
The Bottom Line: Safety First
Always verify the ammunition type matches the firearm's chambering. Refer to your firearm's owner's manual for explicit instructions regarding the approved ammunition types. Never experiment with mismatched ammunition; it's a risk not worth taking. Gun safety should always be your paramount concern.
