I own rifle cases like that, and none of them would suit my needs. While long enough... they are just too thin (I have lots of leather straps, floggers, etc).
Something like this http://www.amazon.com/Duffle-Bag-Canvas-Israeli-Rothco/dp/B001KWK7GY/ is a much better fit. Problem is, I want to be able to organize everything. That would be able to hold all my toys... but it would be a huge mess.
Be great if I could find a bag like above, with a bottom-pocket (Like many suitcases have) and inner-dividers.
