I am using various powders. Primers are seated below flush as normal. Bullet still tumbled with a clean bore which has had the Dura Bore Coat treatment a few months ago.

I did notice that when I pull the trigger the hammer causes the bolt to move 0.015” forward. This seems to me that it may indicate a headspace problem which might be causing my occasional misfire. This is my first and only lever action so I do not know what is normal but this sure seems excessive and suspicious to me. Is this normal or likely a headspace problem?
