Hello from New Jersey, just joined great web sight.
I was cleaning up my basement and cleaned out some cabinets that I had put about 30 boxes of Remington Express and Winchester Super Speed Mark 5 12 gauge shotgun shells in about 38 years ago.
I put them in the cabinets and any time I went target shooting or hunting I would just take the new ammo that I bought.
These shotgun shells were all bought in the middle 1960s.
Now that I retired I was getting rid of stuff in the basement that I did not use anymore.
I knew the shells were there and never bothered to use them.
I opened each box and checked each shell, the boxes and shot shells are in mint condition.
I decided to take a box each to the range.
I fired them out of my over & under, side x side and pump shotguns.
Would not take a chance in my semi autos.
All went bang and they smelled great as the were ejected.
Todays Remington Express and Winchester Super X 12 gauge high brass shells do not smell the same after fired, maybe they use a different powder now.
Ah the good old days came back when I fire those old shells.
