A Pelican iM3100 Rifle case HAS rollers. It also also falls under the dimension requirements for regular non-oversized checked baggage saving possibly $150 US EACH WAY.At least that's how it worked out for me on a recent domestic US flight - the (edit: savings on) baggage penalties on one flight more than paid for the case!!!
This is my Pelican iM3100 before I cut the foam. I could easily fit 2 barrels & 1 scope. 2 Barrels and 2 scopes might be a tight fit but probably do-able. But scopes can be taken on carry-on baggage anyway.
