I've been extremely pleased with the Ruger American Predator rifles I've owned and shot in 308, 223, and 6.5 CM. Enough so that I bought one of them in 22 LR. It was a disappointment. My 10-22 is more accurate and I did have ejection issues. The brass would extract, but unless you pulled the bolt back vigorously it would not eject. I didn't keep it long.
I did eventually replace it with one of the Tikka T1x 22's. Now that is a shooter. I paid $440 for it, and considering the huge improvement in accuracy consider it money well spent. Before buying this rifle I always thought most of my rifles were more accurate than me and that my shooting skill that was the limiting factor. This rifle proved me wrong.
