I just FL sized once fired 6.5CM Peterson brass in a 6CM due to neck it down. The brass was annealed before sizing and then mandrel expanded afterwards. I did not measure the brass lengthy prior to doing any of this, I assumed it would need to be trimmed. I just measured the cartridges and they are measuring between 1.905”-1.907”. Book trim length is 1.910”. Is this usually the case (no pun intended lol)? Is this brass still ok to be used? Thanks
