I've found that the Havalons or similar work pretty well on closed-cell foams, but I've found my results to be absolutely horrible on the regular open-cell pelican foam.The Havalon knives with replaceable scalpel blades work just fine for detail work, just lay the foam on the floor or a hard work table and make plunging vertical cuts. Checking SN#'s isnt always a TSA requirement, but should be a personal accountability check when you get your case back in your hands on the other side. If you leave the airport and then find out shit is missing thats more difficult to prove. Its not that hard to open those cases without picking locks.
EXACTLY.One personal preference I'd change is that even though it "looks funny" I orient my rifles stock down to the wheels as he did but scope up towards the handle versus down towards the bottom of the case. That way as the case gets set down or chucked around by baggage handlers the weight of the rifle isn't being absorbed by the scope. May never make a difference in real life, but it just makes more sense to me to have the scope up when carrying the case.
