I've been using this Condor Double rifle case in 50" for the past 3 years now and it's done everything I've needed it to. Looks like they don't carry the 50" anymore unfortunately.
I throw it in the bed of the truck (with a campershell) every time I'm taking the rifle anywhere and haven't had any issues at all. Good sturdy zippers, stout velcro, plenty of extra pockets and will fit 2 scoped rifles just fine. The removable pouches on the front are nice and big enough to hold all of my junk. Silencer in one pocket, big box of reloads, a couple of magazines. If you ever had to pack it anywhere, there's 2 shoulder straps like a backpack that can be pulled out of a side pouch, but I've yet to use it that way. I pulled them out and they seem sturdy though.
