Oh, dude, the barrel twist rate for a Remington 308 model 7400 is typically 1:10. It means the bullet completes one full rotation in the barrel every 10 inches it travels. So, like, it's important for accuracy and stuff, but don't lose sleep over it, man.
The bullet will rotate one full turn in ten iches.
Check the date code on barrel ;) There's information on the Remington Society of America, check related links.

Remingtons are dated by a letter code on the left side of the barrel, not the Serial number.

What is the value of a 03 a3
There have never been any recalls on the Remington Model 742 that I'm aware of. The Remington 742 is now an obsolete model and was replaced with the Remington Model 7400. The bolt received an upgraded design along with the magazine catch/release. At one time Remington was offering a Model 7400 as a replacement for the Model 742, if you sent them your Model 742 along with $350.00. Is there a problem with the 742 that you have?
