It doesn't matter that much to me either, I just do not care for wise a$$es. Especially someone who thinks they are are the only one who knows physics, sound speed in 416R is a constant at 13,333 mph, which in his tiny brain tells him that it has a constant frequency, which it does, if it is dormant and nothing ever changes. Oh, and don't give me that **** about it will weigh 8.97 pounds, you have no idea how it will be shouldered, threaded, contoured, or crowned, therefore no idea what it will actually weigh until its done and weighed. Its also possible for a human to actually hear 21.87hz, after that then you break it down in to its molecular construction which varies from one maker to another. The only thing I see you're good at is reading someone elses theories and using math to come up with a pathetic argument, when I think you should do some more reading on resonance, hertz, and wavelengths and see how they are effected by size and shape. Lefty your right most of my buddies that shoot IBS use 28" barrels for 300wm and wby, , the one I learned the most from had a 28" barrel chambered in 30x284, it wasn't enough, he had it set back and rechambered in 300wm and it finished at 25.75", only shot the 210 berger at 2780, but his grandson won 4 or 5 1k junior championships, and to this day will still print 3.5" groups at 1000yrds.
