I've done it a few times and really didn't care for it. I ordered a 2-piece with identical specs to my one piece bow and fit a Pelican Storm IM3100 case to it so it can hold my bow, quiver with arrows in it, binoculars, arm guard/glove, game calls, knives, a couple dozen extra arrows, a small tackle box of extra points/pieces/string wax/spare strings, my bow square, concealed carry weapons, and a big ole .44 mag revolver. The firearms and knives need checked with TSA anyway for hunting so I just put it all in one big, crush proof, idiot proof, waterproof case with cutouts so I can't loose/forget anything. It'll even float for when I go on canoe hunts.
I made the arrow holder strips on the ends out of the cutouts for the bow quiver and the center one is two pieces from the binos and arm guard/glove/tackle box/game calls cutout. The edges aren't super straight and pretty but it kept me from buying a whole extra insert foam kit and it works like a champ. I put 13 cuts on one set and 12 on the rest at a slight angle. Then I positioned the 3 foam pieces for my arrow holder so that they at least partially cover and squish down the knife/binos/arm guard sections which of course also holds down the bow and quiver in three places too. It's pretty secure and solid.
Exterior dimensions of the IM3100 case are 40"x16.5"x6.75". That's a lot of stuff to fit in such a small package and still have extreme levels of protection, a floating case for canoe trips, TSA approved transportation for knives and guns, a way to travel by car where I can toss luggage on top/around my expensive gear without care, and a way to quickly at a glance make sure that
everything that is an
essential for hunting is present and accounted for BEFORE leaving home for the trip or returning. No accidental whoopsies that result in an unprepared hunt or gear left behind. The downsides to building such a travel case are it is a little bit of cost to buy a specialized case, and it will result in an extra checked item if flying over stuffing it in a duffel bag or cooler with other equipment.
