Had a friend sneak in a Vickers with tripod and accessories into his room at 2 in the morning. His parents wouldn't let him buy any more guns, but once in the room, it had so much stuff in there he could just claim "it was always there". And it worked too.
Many a gun nut has been asked the question "Is that as new gun?"
"New? Nah, I just don't take this one out much"
or my personal favourite for milsurps, "What the f### is that! It must be new..."
"Oh no, its actually quite old!"
Whether any of these actually worked might be up for debate. Being that milsurp collecting is a disease, It can be hard to stop yourself. That nice Mauser or Lee Enfield looks good and makes you happy whether you are eating a steak, or a bowl of KD.
To be serious, I don't recommend frivolous spending on anything, but like others here, no booze, and no smokes freed a lot of cash up for me. Any money you spend on milsurps *should* be a good investment for the future, if you don't blow your budget from the water in the process of accruing your collection. The value of guns as an investment in Canada has been discussed here before, its not something Im going to delve into. Enjoy them while you can, pass them on to interested parties that will take care of them, its that simple IMO. As for not shooting the gems, in my case, they came along after the shooters, so I never needed to shoot them, some have been shot by me, but only out of curiosity. The good ones aren't coming to the range, plenty of shooter grade stuff out there. (unless you need to shoot that No.4T, or 1903A4, a gentle range trip is understandable, but anyone who has one of these won't be doing that very often)
