Can someone explain what exactly is being "broke in". ie. names of parts inside the receiver. It would seem to me that it wouldn't make a difference if you shot 100 light loads vs. heavy loads. either way the gun fully cycled 100 times. wouldn't shooting the lightest loaded shell cycle the bolt completely back and stop, then return forward. What I'm getting at is that lightly or heavily loaded, the gun will cycle COMPLETELY.
Love my SBEII
