Ok, I admit it. I am a cheapskate. I'm so cheap that....
1. If I see a bunch of wheelweights lying on the road at an intersection, I will pull over and pick them up. I keep an old coffee can in the trunk of my car to hold the weights. I have learned that the best place to look is along highway exit ramps. It seems that loose weights are frequently thrown from vehicles as they decelerate after leaving a highway.
2. I have gotten boxes of lead from my dentist (used for x-rays).
3. When I am buying a new tire I will slip an extra $5 or $10 to the mechanic in exchange for a bucket full of old weights.
4. I collect brass at the range...even those cases I cannot use (because you never know when you might get a good deal on a gun that can use the brass). Be prepared!
5. I purchased one of those gas check makers for $100 for .30 cal. I only need to make 2000 more before I will break even
6. When I walk downrange to get a target, I check the berm for bullets I can melt down. I have to admit that it is a bit of a hassle to melt the lead out of copper jacketed bullets, though.
7. I have purchased really old but full cans of gun powder that were used as displays in gun shops. The powder might be old, but it still works fine and I have gotten some great deals. I got a pound of Reloader 21 for less than $4.
