I am relatively new to reloading. I am currently trying to reload some .223 Lake City Brass I purchased off Gunbroker. I understand the military brass has a crimp on the primer. I thought I could simply use a small primer pocket cleaning tool to clean out the primer pocket, but this doesn't seem to be the correct thing. I tried cleaning all the primer pockets, but I don't think I'm removing anything. I am using a Lee Auto Prime to prime the cases, but I am having difficulty and suspect there is another step I need to take with the brass before priming. What is it?
