Where are some places I can get a lot of lead shot? I need about 400 pounds. We are using it to make simulated magazine weights for our Tac Vests. A fully loaded mag weighs approx. 1 pound. I will take plywood, router out the middle, put lead shot in and cover with hot glue. This works great. I got the idea from some 'training mags' I found in the States. I have heard you can get it from Canadian Tire and other like-stores. I need to be able to buy this locally as well (Vancouver). Anyway any help would be appreciated.
