I deeply appreciate all the information that forum members have provided, and the advice is certainly appreciated and not lost on me. At this juncture, it seems that the best path going forward is to consider shooting the gun with reduced pressure 41 cartridges - I still have some questions regarding using reduced 41 magnum loads versus 41 special loads, and will carefully consider the options and do the homework. If only I could elicit a response as to who did the original work - but to date, that info is not available. The benefit of belonging to this forum goes without saying.
