I've got a question about reloaded 12 ga. shells. I'm new to reloading, did my homework and followed a recipe, however, the first 50 shells I loaded and fired has powder burns on the outside of the hull. I'm wondering why this is happening. Here's my recipe: Once fired Win AA+ hulls 1-1/8 oz. #7-1/2 shot Fed 209A primer Red Dot Rem Fig8 wads The Red Dot is fairly old, from the early 80's. Is it the powder or are the wads not sealing the powder correctly, or something else? Any help would be appreciated. Jimski
