[QUOTE="J E Custom, post: 1061940, member: 2736"] You are correct about the effective barrel length being the point that the bullet touches the rifling and that would be where the barrel starts to have an effect on the bullet. A short mag would have slightly more rifle bore than a standard magnum even though the barrel was the same length measured to the bolt face. The measurement to the bolt face started hundreds of years ago when all weapons were muzzle loaders and you measured all the way to the breach block or back of the chamber. ram rods were marked with this dimension to prevent loading with no powder or an over charge. This method of measuring barrel length has stuck and when cartridge guns came along it did not change. If you think about it, on modern weapons the barrel tenon is flush with, or recessed to clear the bolt or action. so the tenon is part of the barrel and the measurement is still very close from muzzle to bolt face. It is also the official way to measure rifles, pistols, shotguns for any barrel length compliance length if required. J E CUSTOM [/QUOTE]
