Pelican is very heavy. I have one for handguns, and a heavy Plano with wheels because I bought it way cheap and have some use for it, but prefer the much lighter weight SKB cases. The Single Scoped Rifle case is sturdy, very protective, comes with several choices of locks, and weighs less than most rifles.
I looked at both SKB, and the Peli Storm, and size for size, the weights were nigh on identical.
When flying, I use the Peli Storm 3100, and can fit both my Chapuis SxS, and my Merkel Helix, or one of them, and a load of other stuff. A friend bought the Peli Storm 2700, and has fitted it out in layers, to take a Merkel Helix, extra barrel, magazines, scope, etc'.
Case, foam, rifle, scope weigh circa 12 kg, which is more than manageable, especially as it has wheels, and I know the rifles are safe, which to me, is more important than the weight, or the extra cost, over the cheaper alternatives.
Case before I swapped the Browning Maral for the Merkel Helix.
