There are a lot of articles and discussion forum threads on barrel twist rate for AR-15s. So why am I writing one? Well, some of the information on the web is very wrong. Additionally, this closes out comment threads we've had here touching on this topic, EMail exchanges I've had with readers, and personal conversations I've had with shooters and friends about this subject. It's natural to put this down in case anyone else can benefit from the information. Or you may not benefit at [read more]
Continuing with the things we are progressively learning about the shooting in Aurora, Colorado, the shooter’s weapon jammed.
The semiautomatic assault rifle used by the gunman in a mass shooting at a midnight showing of the latest Batman movie jammed during the attack, a federal law enforcement official told The Associated Press, which forced the shooter to switch to another gun with less fire power.
The official, who spoke on condition of anonymity to in order to discuss the investigation, said the disabled weapon had a high-capacity ammunition magazine. Police have said that a 100-round drum magazine was recovered at the scene and that such a device would be able to fire 50 to 60 rounds a minute.
As I have pointed out, the rifle wasn’t an “assault rifle” (since it didn’t have selective fire capability) and the phrase “semiautomatic assault rifle” is nonsensical. It is a contradiction, since a semiautomatic rifle cannot be an assault rifle. The police and media are both to blame for sloppy work.
But note also what I said about mass shootings.
“… the most frequent choice for such shooters in order to achieve effectiveness seems not to rely on magazine capacity, but having multiple weapons and magazines.”
Unlike me, he had a crappy rifle and his jammed. He also had a high capacity magazine. It didn’t matter. He reverted to use of multiple weapons. It also won’t matter to the anti-gun lobby. They will continue to use this as yet another example of why high capacity magazines should be banned.
