During my last four trips to shoot at the Range I have had my stapler borrowed twice. I could not believe anyone would go to the Range to shoot without a stapler and Targets at a minimum.
My Range Gear has evolved over the years. I now have an old plastic tool box that is approximately 8" wide X 9.5" tall X 21" long. This one had my Evidence Kit in it years ago. I have another one that looks just like it, that has CRAFTSMAN on it. In the box I have the following items:

Stapler
Box of 9/16 Staples with a Rubber Band around the box
Impact Sport Electronic Hearing Protection
Target Kit (Plastic box with 3x3 Post it Notes, 1" Painters Tape, and a roll of Scotch Tape)
4X4 Wooden Block 9.5" long (I set my Shot Sack Sand Bag on it)
Mini Shot Sack Sand Bag ( I had these sewn up at the Upholstery shop, they are about 7" long) (10" x 10" Canvas before sewing)
Small Brick Sandbag for under the Butt (2" x 3" x 4")
Big Brick Sandbag mainly used under the butt when cleaning (3" x 4" x 6")
Bubble Level 10" (a good quality one)
Scissors (To cut different size targets with)
12" Ruller (I use it to put lines on Targets)
Lead Pencil
Good Calculator
Laser Range Finder
Extra 9V Battery for my Chronograph or Range Finder
2 Black Spray Paint Lids (Used on my Bi-Pod feet)
Plastic Cutting Board ( I place this on the concrete bench using a Harris Bipod the above listed spray paint lids slide on the plastic board) I plan to cut it to fit in the box. My Gear Box is still evolving.
