All thank you very much. By the grace of God I was able to remove the round and not cause much further damage.
Summary: triple checked what position the bolt was in when it broke off. Luckily the bolt was completely up and looking at how much it had moved to rear vs normal position. based on the posts above and further reading, I believed that the potential for the firing pin to slip and have a discharge was very low. I proceeded to try to take the barrel off (2nd attempt). The first attempt the barrel would not move even with the wrench. Fortunately, on the 2nd attempt it came off with minimal force hand turning. As the last thread engaged the round fell to floor. Upon closer inspection it appeared a small piece (1/3 size of a small rifle primer) of black pot metal (the raw metal showed Granularity) also fell out from the area where the lugs engage. My best idea is that the small piece of metal had caused the lugs to bind as I attempted to clear the chamber. I felt zero pressure or any restriction closing the bolt and with the brass FL sized on a small base die, it falling out as it did, and the mysterious piece of metal my only conclusion is that it was caught in a bind on the upstroke. Interestingly enough the safety lever snapped when I cleared everything and function tested it. I'll file this situation away, but to say you couldn't get a greased BB up my *** was an understatement. The muzzle was pointed in a safe direction and extreme caution was taken every step but things happen. I'm just glad no one was injured and the only damage is the cost to have the bolt tig'd. Thank you very much everyone. I value all the knowledge and insight this forum has to offer. Take care!
