This elk season in CO will be my first using a ML, a .50 cal T/C Omega. I encountered the locked breech plug during my initial session with the rifle in May. Talk about being locked!
It took two guys holding the rifle while I got up on the bench at the range and put some serious torque on the tool that came with the gun!
I was using 777 FFG... This thread has been very educational.
Thanks.
