Thanks
I checked 5 handi rifles and 4 shotguns and I have one shotgun and 2 rifles, that will open with the hammer cocked, (a 22 rimfire and the old 223 I just worked on. From the responses especially from so many experienced people, its not clear if the manner of reassembly could cause the problem. If anyone has experience with isolating and correcting the cause of this characteristic, let me know.
