My .30-06 XL7 is a tack driver. It's hard to argue with consistent sub-MoA groups. (Accuracy is fantastic with the factory stock's pressure points. I also tried a Boyd's stock, but my barrel didn't like to be free-floated.)
However, I have a Marlin barrel, and a Marlin production rifle. The newer X7s (Remington barrels and production) have very mixed reviews.
