Everyone where I hunt ended up using boxes.This tells you something. I use a box and the rifle is kitty corner. My 24" barreled magnum fits. Others have had the barrel shortened. Another clever answer was to criss cross bungees so the full length box would bounce sideways when that tree jumped out. My lid is hinged on the front like everyone else's. My box covers the front rack. The rifle section is like a hard shell rifle case so I get a fair bit of storage in the rest of the box. What ever you do, don't mount the rifle so you can not bail easily.
