Yep, and buying more every day!
Put on your "Tinfoil Hat" boys we're going for a ride....a friend of mine that buys into the Bermuda triangle, aliens and other wierd stuff says that the stores now keep track of who buys what ammo so the government can guesstimate who has what weapons. Sounds logical enough. Well, he's says the government pays special attention to those that are buying large quantities of buckshot and slugs. Fasten the chin strap on your "Tinfoil Hat"....He says he buys #8 and #7 1/2 bird shot and then uses it and 5 minute epoxy to fashion his own...????????? ...I guess that would work but they would still know you had bought a lot of ammo and owned a 12 ga. (whatever ga.) shotgun. I think the epoxy fumes have gotten to him.
I believe if I was going to do something like that, I would just melt the lead and pour it in a mold. Buy or scourage some fishing/tire weights to make up the slack.
Shoot, I'm still shooting up a some ammo that I aquired 42 years, 2 months and 12 days ago....I write the date of purchase on it when I get it.
