question - anybody know what the bore is on the cz 527 7.62x39 - 311 or 308??

.311 on mine. While it shoots Winchester 123 grain sp's (which I believe to be .310") very well (almost 1 MOA), it really shines with 150 grain .311 bullets made for the .303 British and cuts the groups in half when shooting them about 2215 fps. Good expansion and deadly on deer to 150 yards or so.

thanks
