Bullseye shooters generally have a pistol box. Place it on the bench and it becomes like a desk to work from. Action shooters[IPSC, steel, IDPA] may use a range bag since they move about the range more .
I'm not doing any competitions yet(hope to head that way though) but I got tired of using the Walmart "plastic briefcase" pistol box so decided to build my own. If I ever start competing, then I'll modify one or build another to meet my needs. The larger has all the size in the world but I wanted something a little smaller to just go to the local range so I built the smaller box.
I was told that the Pachmayr boxes need to have the shelf support adjusted lower in order for scoped guns to fit in the clamps.
A lot of .22 bullseye shooters still use them even though they were designed before red dots became popular for competition.
A member in my .22 club has several of them for sale.
If anyone is looking to buy one then send me a PM.
