I was given a old bolt action .410 shotgun from my father and it is alittle on the old side. i do not know the age of the gun i know he bought it when he was 14 "he is 51 now" he bought it used so it is at least 37 years old. now the gun has not been fired since i was born i am 22 so it has sat for quite awile. i have cleaned it very well and went over it and it is in great condition i can not find a reason not to fire it, but i am a tad bit concerned of firing it since it has sat for so long. is there anything i need to check or make shure before i put the first shell in it in over 22 years.
