If I am not mistaken, Wouldn't longer barrels on smaller cartridges be worse for distance? I would rather shoot a paper wad out of a 12 inch straw than a 24 inch straw. It would take more energy to get the paper wad to fly out of a 2 foot straw than it would the 1 footstraw. Or wouldn't this make alot of difference for rifles. Just used the straws for comparison.
