I have probably fired 300 to 400 rounds through my VC .600 without any problems. I say don't believe everything you hear out there. I am obviously bias, but I would say that I much prefer the look and feel of the vc compared to the heym. I think heyms are overpriced. In fact, out of curiousity, I am going to contact Ken Bush and Kebco just to see if there have been any complaints about the VC. I bet there have not.
