Used to. Will again.
In 76/77 I lived in Galena and was into muzzle loaders(have yet to kill with one!). At some previous time they had ripped a bunch of 3 inch lead conduit out of the runway and dumped it in a pile over the end of the dike. At the time the Air Force was still flying F-4 s out of there as Bear interceptors until the F16s from Great Falls could get there and used 3 arrester wires and sometimes their poop chute to stop on the 5,000 foot runway. I suspect the junk was part of this system. Fun to watch those landings. Pilots were a might twitchy even after a couple bears at the club. We lived in on base housing and had privileges.....
At any rate my cruiser ax and I salvaged several hundred pounds of the discarded lead melted down into ingots on the kitchen stove. Prolly not all that healthy!
Last time I used any of this was as a gill net anchor several years later, enclosed in a 7x8x9 inch IIRC plywood box. Weighed 68 lbs. The Manley Postmaster was overjoyed when I sent it to myself there, as I was between jobs and spending a couple months at my cabin. He also enjoyed the 30 something boxes my wife and I sent to his 8' X 10' post office.
As I recall, his exact words when I walked in the door a couple weeks later were "You SOB(abbreviated), I almost ruptured myself!" I ask you, is that any way a public servant should be addressing a client? Fortunately he was also the bartender, and it was only about 8 steps between jobs.
I really should unbox that lead one of these days. As soon as I get a 1/28 barrel in something. That compromise 1/48 TC used on the Hawkin 50 and Seneca 45 ain't worth spit, but they are fun to shoot even if the aren't accurate with either ball or Maxie. Probably should ask my Denver brother for the .50 Hawkin back after these 16 years. He went and bought an in-line, the putz. Nowhere near the record 21 years he kept the .270, now an '06 caribou killing machine here in Kotzebue.
