I have that same case and I am very pleased.
They are specifically designed for the stated purpose and quality is very good. They look like a Boyt and I think it is darn near as nice, for less money.
One thing to note is that it looks like they have a brass buckle, but that is really only for aesthetic purposes. The black plastic/polymer buckle is actually very practical and works well. The case is well padded and uses quality materials.
I know the original poster said he prefers a zipper over a buckle - I actually prefer the “slip” design over a zippered case for non-bolt guns. I’ve scratched guns on metal zippers and think the slip is more efficient. It would be difficult to improve on the Cabela’s case for the desired use, and I’m not a Cabela’s fan boy. Really, really nice little case.
