My son and I just got CVA Hunterbolts, and as stated above, they shoot, once you find what they like to digest. (We are still experimenting.) Will be trying them out for "real" Saturday when Minn ML season opens. I'm 75 and didn't figure I wanted to invest $400-$500+ as I wouldn't be around long enough to justify the cost. Looked at several, and decided we wanted a closed bolt rather than one that fires from the open bolt. Not sure the 26" fluted barrel is worth the extra cost, but that's just my uneducated opinion. We had been shooting traditional 50 cal. before.
There some things that I see where they cut cost, such as the plastic thimble for the ramrod which I can see as breakable part. If it works and shoots straight, what difference does it make if it cost $l50 or $550? (You could buy 3 of the $l50 guns for the same price.)
Good luck with whichever one you get.
