ok guys i am in need of some advice. about three weeks ago my grandfather passed away and him being the old time farmer that he was he had three guns. the 12ga. and .22 we brought home with us while we were cleaning the house. the .303 is at an uncles. the thing is we found a 25 count box of #4 ACE shotshells that had been purchased for $3.49. now from what limited knowledge i have are shotshells not about a buck a piece now? these shells are very old by my calculations and my father has deemed them not safe. are they safe? can we use them? i personally am not going to take the chance even if they are. my question to you guys (and ladies) is what is the best way to dispose of these shells safetly and quickly? any help is greatly appreciated.
