If there is an advantage for me with the l.o.m. over a hard case it is "traveling light". I shoot doves a lot. I don't care to lay out a big hard case on my tailgate. It would look pretentious in the crowd I shoot with. I don't need all the accessories for an afternoon shoot.

I have some hard cases, but for vintage guns prefer the l.o.m. Just a personal preference, that's all.
