Yes...try running the cases in the sizing die just enough to let the expander ball go thru the neck and back out..use a little lube and clean the neck out..then re campher the inside of the mouth of the case....if your dies don't use a expander ball ,try cleaning the inside of the case neck with a old bore brush in a drill for a couple of seconds.......also clean the seating stem inside area where it contacts the bullet to make sure it makes good contact evenly with the bullet I wouldn't worry untill the same problem shows up in the second loading.....then it could be mismatched sizing die to your case neck wall thickness and expander-if the die has one....some dies are tighter and have different expander sizes from brand to brand and even in "manu. runs" of dies...according to the life of the reamer-tooling......hth...good luck and good shooting-loading!!I have just for the first time used a set of redding dies in .308 cal. I noticed that I had a small ring and some scratches on the bullet when seating them. They were sized with rcbs dies some time back. Only thing I can think of is that the rcbs die sized them small making it tight to set the bullet or that the seating die has a rough place in it. Has anyone seen this
when seating bullets.
