Was there an actual issue with this chambering and what might need to be done gun smithing wise if aquiring one? I see no mention in Roger Rule book about failure to fire or safety just that it was dropped from production due to lack of interest. I am looking to purchase but don't want function issues. There seems to be head space controversy. I hunt with this round and find it perfect for my type of application. Even moose it has been a tremendous performer. Thanks in advance.
