I've had a midway "drag bag" for a few years now and never had a problem.
I use it when I don't feel like lugging a hard case around or when I don't need the protection of one. Even with a ~16 lb bolt gun and a 16" barrel ar (don't know it's weight) I've had zero issue's... apart from the string around the zippers, but nothing a little paracord didn't remedy.
And that larue soft case looks really nice BUT... $230?? I mean, IF it came with the Pelican that would be a hell of a deal but damn... Having said that if they go on sale for say, ~125 I'd probably get one..
Anyways, check out the Midway drag bag I got mine for $60 or there abouts and it has enough room to store just about all of my range stuff. 2 scoped rifles, ammo for both. Spotting scope/ small tripod for it. Hearing protection, staple gun, the list goes on.. It may weigh 40+ pounds and be unwieldy fully loaded but it's held up to all of it.
