I have a question, more I think in keeping with the OP -
The consensus seems unclear on whether or not it will decrease in availability, but lets just say, it will.
I dont have anything that shoots x39 (I know, I really should), but have been considering picking some up for the sheer sake of having it - and have advocated the same to friends and family, even those who dont shoot (I get some weird looks).
The thrust of the argument is; spend 180-200 bucks now, and when the stuff dries up, sell it for a profit. Frankly I'd rather just buy it cheap now and shoot it, but the reality is if it goes off the market, it will be more valuable.
My question is - how much more valuable. To you SuperMen (I salute you) with the ho-jillion cases squirreled away in your basements/garages/manvaults, are you sitting on a potential fortune?
ALso - with regard to value; I'm living in a rural area. I gauge the ammo popularity by what gets left at my local range; to date I've found two x39 cases in two years. Something tells me there are more .303's than x39's here - would an increase in price/rarity be felt less in rural areas as opposed to urban settings?
