Probably 15-20 gallons or more. It was in about 2'+ of the bottom of what looked to be an old herbie curbie. All sorts of calibers. I saw 9mm, .45acp, .40, .223/5.56, and many others. The guy said that he didnt really know all of them, but admitted to a bunch of .357 mag/.38 and .45 Colt. He said there was also a bunch of .22lr brass in there as his original goal was to sell it for scrap. He has a nice range set up beside his house and said that a lot of people shoot at it. So, I ask this with the idea that I hope to one day come across this guy again to buy some(although I dont know when/if that would ever be). How much is random brass worth? Do you buy it by the pound or gallon? If so, how much is reasonable for brass? I am only guessing that it is once fired since he obviously doesnt reload. Rod Wanna kill these ads? We can help!
