About six years ago I was at the range and a partially disabled chap was picking up brass with a gadget known as a "Gopher". I don't bend at the waist any more, so right then I decided that I had to have one. I now have three, and will not shoot a semi-auto without one. I keep one in my garage workshop, one in the truck, and one at my buddy's ranch where he has a range. I think that they are still available on Amazon and EBay. I bought mine at Walgreens, but they no longer carry them.
I place my brass collection bucket on the ground, and then pick the cases up and toss them into the bucket without having to bend over or kneel down. It takes just a little practice to get through the learning curve, but it comes to you pretty fast. It's amazing how quickly one can recover a hundred cases with comfort and little effort. The last one I bought was $10.00 plus tax. On the off chance that you don't warm up to it, at $10.00, what do you have to lose?
