[QUOTE="DJ Fergus, post: 1873847, member: 93895"] My personal findings May differ from other people's findings. What I have observed is sometimes slower burning powders in short barrels leaves alot more powder fouling in the barrel. I can't prove it but I have my suspicion that this speeds up carbon fouling. I have observed increased carbon build up on the muzzle face when running a muzzle brake and more build up in the muzzle brake itself vs running faster burning powders in short barrels. If you are shooting later in the evening, you will notice the muzzle flame upon firing will be more lenghty vs a faster burning powder in a shorter barrel. You get a more complete burn in a shorter barrel with faster burning powders vs something like retumbo or n570. All that being said, there are plenty of folks running slower burning powders in shorter barrels with success but bore size has influence on this also. Let the rifle tell you what it likes. But if you are trying a slow powder in a short barrel and find yourself having to clean it quite often to maintain accurracy, then you may consider stepping to a little faster burn rate. [/QUOTE]
