Loading for 223 semi-auto is new to me. Some once-fired cases that I purchased have the rim dented outward in one spot. These are not from my gun so there is no way to tell for sure how the dents got there but it looks like it may be due to the extractor. These dented rims almost prevent the case from fitting in a shell holder. For sure these cases cannot be resized properly as they ride very high in the shell holder. Is there a way to correct these cases or should they just be scrapped?
