When I first moved to Omaha, I used to make pocket money buying Savage 340 series rifles in 30-30 and 223 for under $150 and selling them to a pawn shop in Wisconsin for $50 more per unit than I paid for them. The pawn broker told me that he had pawned and resold some of those rifle four or five times, making a significantly greater ROI than the 25% to 50% that I made.
