I have been looking for a way to transport 3 rifles on our elk hunt this fall and was either looking at spending a boat load on Pelican cases or building my own. The case is 48" long, 18" wide and 14" tall (no more than 2 large pelicans stacked on top of each other). It is made of 1/2" plywood and some other scrap 3/4" wood I had laying around. I lined it with cheap carpet that I picked up at Lowes and lined the areas that contact the rifles with some suede I had from another gun case I built. For the wheels, I used casters that I welded so they wouldn't spin. I ended up spending about $75. I still need to figure out a way to strap down the guns so they dont rattle around. I made sure to make the smaller boxes inside large enough to hold a 50 rnd ammo box and bipod and is also big enough to hold a range finder in its case. It may not be airline approved, but it's going to be riding in the back of a truck under a topper, so that doesn't matter.
