The 6.5 CM hater crowd is just as irrational acting like they had something personal stolen from them when you compare ballistics data. Many seem to get some kind of irrational personal enjoyment by provoking arguments with less experienced shooters which they then push to the brink of fist fights.
To me shooting is something I enjoy, I spent years developing my skills. I'm not the Guinness Book of World Records super champ but I'm also not a noob, or someone with a persistent accuracy problem. What I don't enjoy is constant squabbling at the range from those who get a rise out of less experienced by provoking them with statements that infer the thousands they spent on their rifle and scope amount to garbage, or the reaction when the maligned jump to it and feel the need to defend themselves to those who are best ignored.
I always feel the urge to tell them "shut up and send it, or go home!" but I know better than that, send my rounds down range and go home, and look for a different day, or range next time. There are few enough long range facilities out there that the combined squabble crowd of provokers and noobs should not get to noise pollute them all on top. If they want to yack and get their respective cow chips off their shoulders any old Walmart parking lot would do.
Terms like wondercreed, or three-oh-hate belong in the mud pit for those who enjoy wallowing in their emotions at a group session. Anytime you have something that enjoys a bout of popularity and an influx of newcomers you will have those who believe their recent investment is now the summit of perfection, and those who want to increase their stature by "having fun" with them; I instead take the approach that it is better to make them converts by showing them that all calibers have applications, that skill takes practice, that usually you get what you pay for, and that what really counts is performance and target results instead of rhetoric and "cheap shots".
