Hey everyone! I started reloading a year ago for .223 and 22-250 and have learned a lot in the process. I pocket uniform, flash hole deburr, neck turn and get great results. I took the plunge and bought Forster BR dies and a Hornady match neck die for my .308.

This morning I ran 20 pcs of once fired federal through the neck die. I noticed no resistance so I placed a 180gn b-tip in the neck and it slid through with room to spare. I then decided to run them through the Forster BR FL die, I could not get the case all the way into the die. The bottom half of the case remains out of the die with zero room between the die wall and the case wall. This first thing I though of was lube so I re-lubed to the point in which I had a depression and still, the case wouldn't enter.

Is there a step I am missing with these Match dies or is it a sign that my chamber is out of spec enough that the cases are over expanded? The point at which it will not enter the die measures .465 and grows to .470 towards the base. I believe commercial specs show that the base of the case should measure .4709 so I am at a loss right now!

Not sure if it helps but the barrel is not "match grade". It is a factory barrel.

Thanks in advance.
