I did something stupid today with the gun and ammo that started this conversation. When DWalt said those were WWII era rounds, I loaded the gun with 6 of them just for history's sake never intending to actually fire them. Well I wasn't thinking when I grabbed up 4 or 5 of my S&W revolvers including this 1946 M&P and took them shooting today. Neither me or my shootin' buddy could ring the gong with this old gun and it was only when I just now tried to clean it that I found that last slug lodged midway in the bore!!! I'm glad it was the last shot instead of the second to the last shot! Apparently that 75 year old powder was too weak to spit that last bullet the whole 5 inches out the barrel. Now, how do I safely remove this obstruction?
