Well, to give you some idea, in my old place, the high water mark was something like 200 rifles, shotguns and pistols. The current high tide mark is more like 50. And that's about 20 too many. I shoot fairly often and half my stuff remains unshot by me! Sad, really.
I've already put together at least three SERIOUS (focused) milsurp rifle collections and then sold them off. In many ways, the hunt for pieces and knowledge about them is more addicting than actually owning the rifles. MY current focus is
Russian
/Finn mosins, but already I've collected all the reasonable stuff. The pieces I'm missing are so uncommon I may never find them. Eventually, I'll sell most of these off too and move on to something else. It's the nature of the beast!
