I used to be enthused about picking brass and finding different ones to. I did collect some for awhile. Don’t have them anymore. It’s great you have yours. Im sure they provide you with A lot of great memories.I remember when I was a kid my father taking me to a local range and I got the biggest enjoyment out of picking up empty brass that shooters left behind. I started a cartridge collection that I still have to this day. All sorts of oddball cases by today’s standards were laying there just for the picking.348 Win,32-40Win,25-35,219 Zipper etc. I have often wondered what kind of rifles these were chambered in and why some of the guys chose the cartridges that they did. I still get these cartridges out from time to time and reminisce about the good old days when I was a kid. So I am glad I picked up all that range brass it has led to a lifetime of shooting and hunting that is priceless!
