How do you see the robustness of transporting a rifle in a softbag inside a Pelican 1750 versus being put into custom cut foam? I have to ship a rifle via FedEx and I am concerned if a softbag would provide sufficient protection to the rifle and optic. Obviously the custom cut foam would be good, but at the same time I assume a rifle strapped into a softbag would provide some protection because the rifle is surrounded by 1/2” of foam and it is strapped into the center of the bag. FedEx has some reputation for impressive results when it comes to testing Pelican case robustness. Any good/bad experiences with softbags like and Armageddon Gear M2010 or Sert or similar?
