[QUOTE="Bart B, post: 686762, member: 5302"] Typical short range benchrest barrels are much shorter and therefore stiffer than 26 to 30 inch ones used in NRA high power long range competition. Their resonant frequency's higher and they whip very little with the 22 and 24 caliber cartridges they shoot. Those longer barrels in larger calibers have a lower resonant frequency and they whip a lot more with larger cartridges burning a lot more powder. Which is why it's more important to not have anything under the chamber part of the barrel except air. Even in short tenon barrels in Win. 70 box magazined receivers totally free floated shoot as accurate as long single-shot actions with long barrel tenon threads. It ain't about stiffness; it's about repeatability. . .for accuracy, that is. What's the difference between consistant and accurate? If you don't think a barrel without bedding under its chamber moves at its junction with the receiver, such barrels are not torqued in tight enough. This proves that humans typically can't do it. But it's not important 'cause we don't hold barrels that way when they're shot. A popular belief with long range NRA high power lower classified competitors. 'Tain't so with those in high master classified shooters winning matches and setting records. [/QUOTE]
