Thanks,Don't think it is the pin/neck causing the trouble now,it has gone beyond the isolated cases,i exchanged eit out from a.223die and nothing changed but had all day yesterday to fool with it since it was raining.I do believe it might be another problem.I do have a Lee collect die set and the resizing die is pushing the brass back just above the web to .371" the brass starts out at .375"-.376"it is sticking the cases in the die. What I did prior was just neckline sized,didn't run the case full length and the third time around to full length resize,it is sticking in the die.the solution would be to ream the die out to.376".I will source a pin or drill bit to check the neck though.w what I am thinking is that I have the barrel set too snug on the go gage,sometimes the bolt closes tight like when crush fitting a .223 round to fire from.if the die is bumping the case back that far,the brass can only go longer until it is 're fire formed.does this sound right?
