Pelican cases are the standard for professional shooters and even military operators. Essentially identical to the Browning travel vault.
I travel to hunt a lot, and have maybe 10 travel cases. These include a Tuffpack, Kalispell, SKB, Browning travel vault, Pelican case, and a few other off brands. I use the Pelican for my own guns when traveling by air. Occasionally I will use the Tuff Pack for wilderness type hunts where the case will be with me out in the weather. I've used all the above mentioned cases with good results, but the Pelican is the best value and best protection you can buy.
