I fired 40 of my own hand loads of .308 out of my Rem700 yesterday. As I was cleaning them this morning I noticed on the neck there is black (carbon). I then compared the amount of black to a factory load which only had a little amount of black at the mouth of the neck. Is this an issue? Have I been letting gas out somehow? Is it due to Not crimping? The black is ONLY on the neck and doesnt continue down any farther. Thanks.
here is my handload with the black on the entire neck all the way around
and here is a factory load (Nosler 168gr HPBT)
