I'n not sure if the OP is looking for a rifle/shotgun case or a range bag, or both.
But, I've been very happy with the Winchester and Wolf rifle cases and shooters bags I've got from Sportsman's Guide, sure you can pay more, but if I crammed any more stuff into mine they'd be too heavy to get in and out of the car. They have held up very well for our weekly range trips. They seem to be the same design, but with different logos.
I particularly like the double rifle case (~$30) holds my Saiga 12 and a pump shotgun or an AK and an AR.
