I broke a band on the 4th slingshot in three days. I expected this, as all four were in the 700 to 800 plus shot range. All four broke within 1/8th inch of the pouch tie, on the inside band. Obviously, that's the stress point in my shooting. I have an idea that someone else mentioned here in the past. Instead of retying or gluing the ends back together, I'm going to place the bands through the pouch, in the normal manner, but then fold them over and glue them togetherwith superglue. The glue should hold fine, as I'm gluing flat surfaces together and not the butted edges like I do when I'm gluing a break back together. That should reduce stress on the band and allow for improved band life. I'll test it on one slingshot and report.
