How does Corbon's quality stack up to BVAC (new / used) or Black Hills for that matter. I shoot both and have had good results. I don't know Corbon. Your opinions would be welcome. You guys didn't tell me I was going to learn a boat load when I joined up...just reading post and putting out my own post. Damn it ! I hate it when I learn stuff when I least expect it and have my guard down!
