I have been reloading for over 45 yrs and have a rule I won't break..that is I don't shoot someone else's reloads. No offense, but I don't know how careful he was when he put them together. Pull the bullets, reuse the brass and bullets..that way you know they are safe. The age of these rounds shoud not be a problem if they have not been wet. I have shot some of my 20 yr old pistol reloads with no problems.
my 2 cents
