[QUOTE="MudRunner2005, post: 1475273, member: 12995"] That was most likely a defective bullet or bad batch. An extra 1" of twist at 223 velocities is not going to cause that much of an issue. I shoot 55 grain bullets through 2 different 7" twist barrels and have never had that issue in thousands of rounds. Please show me links to these studies you talk about... The cartridge chamber dimensions are the exact same...HOWEVER, a 5.56 NATO spec chamber does in-fact have a longer throat dimension and different leade angle than a commercial .223 Remington chamber...Thus allowing you to shoot .223 Rem in a 5.56 NATO chamber, but can cause pressure issues if you shoot 5.56 NATO ammo in a .223 Rem chamber. This is fact, and not up for debate. If you don't believe me, then I suggest arguing with the people who designed and spec'd the differences between the 2, and tell them you think they're wrong. Nobody said your gun would blow up, but it can... And it can cause problems. Just like shooting commercial .308 Win ammo in a 7.62x51 NATO chamber CAN cause issues because commercial .308 Win brass is thinner than 7.62x51 NATO brass, and the excess headspace in the NATO chamber can cause stretching that can cause a case rupture.
