Heck ya they are worth something!!
I am not sure where you are at, but you could just stuff them in a flat rate box and send them my way!!
Seriously, let me know how many you have and what you want, and you might have a deal!!
Of course, I shoot a 1911, so don't have to worry about the cartridge not being fully supported.
I am really not sure what the situation is with the Glocks. I don't own one, and have never loaded for one, so I am not sure what precautions need to be taken.
