Recently built a Traditions sidelock rifle. Cleaned barrel, drum and nipple of manufacturer oils. Popped a cap with piece of paper at muzzle end to ensure no obstructions then used dry patch to make sure no oil or other residue. Went to range and loaded 75gr 777 FFg (brand new), lubed patch and ball. Cap went off but no ignition of powder (2 attempts). Used nipple pic to check for obstructions. Removed and checked nipple. Removed drum screw and inspected. Tried pouring small amount of powder from a 22lr into nipple cavity then re-installed nipple. Popped another cap and no bang. Went home and throughly cleaned barrel, nipple and drum. Shinned light into drum and could see entire barrel from the muzzle end. Obviously, fire from cap is not making it to powder. As a newbie to muzzleloaders, i dont recall any of my research that had an additional loading step that involved ensuring the powder reached the bottom of the barrel and to the drum before loading patch and ball. When loading powder, shouldnt grains funnel to bottom of barrel and into the drum area. Or is there something else i am overlooking?
