I was shooting this weekend and made a great observervation. I have a cz550 that is box stock except for the Mcmillan stock. This rifle has been a shooter since I bought it. The interesting part is it's missing rifling for about 2 inches on one side about 14 inches up. This rifle out shoots my two custom built ones consitantly and the cold bore is dead on. Now I'm as good as anyone at over thinking things and trying to fix them with money or technology but in this case I've gotta say I love VooDoo!
