Like him or not, Bill Calfee was a renowned .22LR benchrest rifle gunsmith. He built many excellent rifles, some of them still used in high level competition. I am not familiar with the circumstances that led to the split between Calfee and those who disliked and often vilified him. He was a gunsmith and shooter with tremendous knowledge and experience. He defended his views vociferously, probably OCD about some things, had some eccentric personality traits, and rubbed some people the wrong way.
If there's anyone here who doesn't have some of the same kinds of shortcomings that Bill Calfee (and probably a lot of other serious people) had, he can cast stones. In the meantime, let Bill Calfee rest in peace. He was a giant in RFBR.
