Quick follow up - I found two Pelican iM3410 cases on Amazon and bought them. Cutting foam is easy but tedious as heck, but this looks to be a terrific case. Thanks for the responses
Heading to Tejas for a deer hunt in January and need to carry my Delta 5, which is 44". Is Pelican the best? Are there other options for an airline secure hard case for a 54/55" interior case?
