Pelican 1750. We have been traveling out west for the last 5 years with them. Both flying and driving from Florida to Wyoming. I have never had a problem with the guns holding zero. I work at Orlando International and see on a daily basis how things get handled. The cases may look like crap after a few years, but the inside is pristine.
I have an Americase Two Gun Safari case. My dad had one of their original two gun safaris from way back when and it was solid for almost 30+ years, I had to replace the foam in his and I gifted it to my hunting partner when I bought my new two gun. It doesnt get much better for cases. Love having another rifle along or extra room for storage in the second rifle bay.
Check out their single rifle cases if you have a large long range firearm. I dont trust plastic cases when am traveling long distances via airplanes. I know quite a few guys swear by the pelicans, but I prefer the 0.08 Aluminum of my double gun case. I am considering purchasing a single rifle case from them as well.
Cabelas has a hard case they have branded, that works great, on par with a pelican and about a hundred bucks less. SKB is good too. Get one with wheels. Trust me.
Pelican. I have the unfortunate pleasure of hauling weapons cases, among many other appropriate sized pelican’s, for a living, and there is nothing better.
While I do like the heavy duty aluminum cases. I have also used pelican cases at work every day for the last 18 years. They get used and abused and still keep delicate equipment safe. I just bought another 1750 case on sale for $170 with the foam inside. There are deals out there. I can fit a scoped model 70 308 and a scoped 30-06 savage with room to spare. I also put all my ammo, knives, and non carry-on items in there when I fly.
