Update: The bushmaster rifle was found in the trunk of the shooter's car. The Sig Sauer and Glock pistols were the only weapons used in the shooting, according to CBS. Now the question is what kind of magazine would allow a shooter to fire "100" rounds in such a short period.
The massacre in Connecticut that's taken the lives of at least 26 people was reportedly perpetrated with a .223 caliber rifle, a Glock pistol and a Sig Sauer pistol, according to NBC.
The shooter was using one Sig Sauer and one Glock, according to CNN.
Altogether, though, it doesn't matter what type of weapon the shooter used. The bottom line is that it was likely a magazine fed, semi-automatic, with enough rounds to shoot "100 shots" in a matter of minutes, according to USA Today.
Magazines for these weapons are generally controlled at 15 rounds, but 100-round drums can be found on the web for the AR-15. The drum is called a "Beta-C Mag," and feeds from two separate 50 rounds sides.
Yes, you have to have it shipped to an Federally Firearm Licensed dealer, BUT, strawman purchases are incredibly difficult to prosecute. You can also go to several gunshowswhere there is little, if any, oversight on purchases.
The caliber .223 is pretty common in the civilian side of weaponry, but it's basically the same caliber of the NATO 5.56 round the military uses (just a little bit more umph on the military version).
The weapons that use .223 caliber ammunition range from bolt-action rifles to the more "assault" type semi-automatic rifles. New Jersey and Connecticut both have strict gun laws in place banning their own definitions of "assault" rifles — and anything over a 10 round magazine — but a simple trip across the border into Pennsylvania can secure weapons illegal in both those aforementioned states, or one can just buy weapons on the web.
The .223 round is slightly lighter than the military grade version, but reacts the same on impact and is pretty much as deadly. It's designed to bounce around inside the body once it makes contact with bone.
The AR-15 is the civilian version of the military's M16 and has been in production since Vietnam.
The caliber is the same used in the DC sniper shootings. It was also used in the Colorado shooting.
