If my "rifle" had only a pistol grip stock on it, then, yeah, it would not save much length to remove the barrel from the stock. But, I have more than a foot of wood behind the tang of my long rifle barrel, and taking the barrel out of the stock does shorten the carrying case substantially.
Its even more effective with half stock guns. My reason for recommending the broomhandle to support the forestock on a longrifle stock was simply to solve a problem of concern regarding having that thin forestock in a large cargo container, banging around from who knows what kind of gorilla activity! I suggested removing the lock and hammer, or cock, to permanently disable the gun, so that the thieves at airports will pass it on, as it has no value to them, if it can't shoot.
Please remember that I represented criminals for a number of years when I first entered law practice. I gained a considerable knowledge of how they think. I prefer, frankly, to share information with honest people here so that you know how to thwart the thieves, without them having a clue that you are even considering them. ( They all like to think they invented thievery!)
I also suggest you avoid the entire Airport problem by shipping your guns to your destination earlier by ground. Your guide or outfitter is used to handling this kind of thing for customers, he already has a substantial deposit from you to reserve a time slot for you hunt, and he can arrange to ship the gun(s) back to you when you finish. The same consideration exists regarding ammo, and black powder. Sometimes you have no choice but to load BP into large rifle casings, like the .45-70, and send a box of those cartridges to your guide, and break them down to put the powder into pre-measured loads for your hunt. I forego sending my powder horns, full or empty, anywhere I can't carry them. They are too easily stolen, or lost, or damaged. I will have done all the sighting in and practice at home before going hunting. At most I will need enough powder for 10 shots- a couple to check the sites on arrival, and the rest for the hunt assuming I can't hit the broad side of a barn. I wish someone would give me a dollar for every ounce of powder I have carried out into the hunting fields over the years that I didn't need. I would be a very rich man, or still a poor man with a fine collection of guns! :rotf: :surrender: :hatsoff:
