Good Ammo; Know your Application

I have read all the reviews up to this point, and feel bad for the guys using AR15/M16 firearms, because they are NOT true .223 Remington rifles. Read this months' "American Rifleman" from NRA, on page 38 for all the good information about the difference between the rifles chambered for the military 5.56 x 45mm ball round, and the civilian .223 Remington rounds. They are NOT the same, though they measure externally the same and will cycle manually the same; the difference ends there. I have fired over 100 rounds of .223 Remington Wolf rounds and Bear rounds, and have been able to acquire less than a one inch grouping while zeroing a scope. The entire group walked right to center. But, I am using a Kel-Tec rifle (American Made) chambered for .223 Remington, NOT 5.56 x 45mm rounds, and firing .223 Remington ammo. This makes for a huge difference as the miltitary round builds more pressure and has a larger chamber for their round ahead of the bullet, causing accuracy and cycling issues for firearms using .223 Remington in place of the 5.56mm rounds (see the article). Bottom line - use the correct ammo, and as one reviewer stated, TRULY learn your firearm, and it will perform as expected. I have used this ammo flawlessly, with the only feed jams coming from worn magazine springs, not ammo. New magazines were jam free. Keep in mind that SAAMI (Sporting Arms and Ammunition Manufacturers Institute) considers 5.56 x 45mm military rounds , "In firearms chambered for .223 Remington, do not use the 5.56x45 mm Military cartridges", and include this combination in their book, "SAAMI Technical Correspondent Handbook" Unsafe Arms and Ammunition Combinations section. Page 42 of the American Rifleman article goes on to detail why using .223 Remington is not a good idea either, in rifles chambered for 5.56x45mm and why. From appearances it is like using .38 Special rounds in a .357 Magnum; okay for target shooting, but for actual hunting or protection, use the ammunition the firearm is designed for using. One other note: ALL gas operated rifles are subject to jamming problems if not properly cleaned and maintained. Miticulous care leads to professional performance; careless use will lead to dissatisfaction and malfunctions, leading to possibly dangerous conditions.
