[QUOTE="Michael Courtney, post: 565361, member: 28191"] Thanks for your insights. Managing fouling can be important to many shooters. In other applications, an increase in muzzle energy is more desirable. Our preliminary work suggests that many bullets lose 200-1000 ft-lbs of energy to barrel friction. For organizations that have already made large scale investments in specific cartridges, increasing powder capacity is not an economical option, and increasing energy by increasing powder capacity carries with it penalties of decreased barrel life, increased recoil, and increased noise. Reduced barrel friction will also increase the benefits of longer barrels where the pressure curve is pretty small, and friction robs most of the benefits of increased barrel length. [/QUOTE]
