I had no intention of hijacking a thread. Any other message forum I have ever been a member of has always prefered using the search function to find an existing thread for answers to your questions or for continued discussion about a topic rather than creation of a possibly redundant thread. If that's frowned upon here and I should have made an entirely new thread, my apologies. Also, my understanding of the term thread hijacking refers to starting any entirely different discussion in a thread someone else started, not continuing the discussion in an existing thread about said thread's topic. If things are different around here, this would be the first place I ever encountered in about 15 years that this is the case.
My issue was a fired round being ejected and two new rounds coming up into the chamber.
