Can someone give me a quick primer on the discussion of "rate of twist" with respect to the .223 Rem? Everything I've read indicates the 1:9 twist stabilzes a wider range of bullet weights than a 1:12. Which weight of bullets does 1:12 not stabilize well? As a practical matter what does it really mean?

I'm pondering the acquision of a new CZ 427 American in .223 but it has 1:12 rate of twist, as does Rugers and Remingtons (at least in their lightweight sporters, which is what I'm after). This fact seems to bother a lot of folks. Can someone help me muddle thru this?

I really like this rifle and the price seems right. Plus it has a really pretty piece of walunut on it.
