I recently got to put rounds through and break in a new CA-3. Before I shot it, I measured a bolt gap of .018". After I shot about 80 rounds through it, the gap measured .016". After cleaning it, I just measured a bolt gap of .014"

I am new to this platform. Is this normal when breaking it in for it to settle that much? Also, if well maintained, what should be the expected wear rate?

Any other general advice is much appreciated.
