Ok guys I have a question and its frustrating the crap out of me.
I have been loading 223 with 68gr Hornady Match BTHP, I set the seater die to 2.260 and starting loading my rounds.
After I ran 3 rounds I noticed the OAL is longer, 2.265 then it would go up to 2.268. I thought maybe my die was loose so I checked it and everything was tight. I then started loading some more and they would go to 2.257. Nothing was consistent, its not like it progressively got longer or shorter it was just random lengths.
I checked all my case lengths and they are the exact same. Im using the RCBS short base AR dies. Anyone have any idea why I keep getting varying length???
