Alex, that was one great sales pitch to recruit some help with the range clean up. Although I'm way too far South to even use those ranges, I'd still like to help with a couple items.
I'll see if I have a clean plastic bucket or two with bails/handles and may be able to find a couple of 5 gallon clean plastic water containers (drinking water type). If I can actually locate these things, then I'll hopefully remember to bring them along to the Colorado Springs gun show this coming weekend - that is if you are still interested in them. Just let me know.
