I'm new to reloading the 223/5.56, I have done extensive handgun rounds. In the process of preparing cases, I just resiszed 100 rnds of once fired 223 and when attempting to case trim I find that the neck is about .210 ID and will not accept the pilot. I had just finished a similar size batch of Lake City 5.56 and did not have this issue, the necks are about .220, which is the pilot dia. This brass is all under max. length and don't need trimming. My question is, will this be too tight on the bullets? I'm using a Hornaday 2pc die set. Any light you can shed on my dilemma will be appreciated.
