Since you are considering the case, I'll give you a brief review.
They are surprisingly nice. I got mine for under $100 on sale. The down side, the pluck and pull foam is very fragile. And simply doesn't hold up. I would budget for a custom foam insert, or attempt the plastidip method. In researching this I stumbled upon an astronomy forum, and they recommended not storing optics near plastidip bc it can cause the lenses to haze up due to out gasing. I have no idea if this is true,. But I have no intention of permanently storing my optics in this case, like they do. Transporting it to the range, on hunting trips, etc shouldn't be a problem.
The case plastic is thick and strong. Close to the quality of my pelicans, close but not quite as nice. For this rifle I have no major regrets or concerns other than the quality of the foam. If this works, awesome. I honestly think it is going to.
I would have zero concerns checking this case on an airline. I honestly think I could run it over with my truck and it would survive. But I am not going to test that.
