Dad and I are going to WY antelope hunting later this year. I will bowhunt and he will use a rifle. I have an SKB parallel limb, double bow case. I know I can fit both the bow and gun in there but how can I secure the gun? There are no straps to keep it from moving around in there. I could use spare clothing to pack tight and keep it secure but I know that once it leaves my hands the TSA guy will tear through it and not put it back properly. Any ideas?
