Re: 223 Remington on a Thompson Contender

Here's a good summary of the issues. But, as this article points out, millions of 5.56 rounds have been fired in .223 chambers without a single documented incidence of catastrophic failure. If you get flattened primers, then you are looking at a combination of gun and ammo that exhibits the effect mentioned here.

When only cops have guns, it's called a police state.

Can I shoot 5.56NATO in a single shot 223 TC?


I have been for over twenty years. But it actually depends on your individual chamber. My pistol will reliably chamber the NATO rounds, but my carbine will not accept about 30 % of them.
