A good friend of mine gave me some advice a few years ago that might apply here. As much as I hope it never happens.....
"Buy them in the order you think they'll get taken away in."
For me, I'm trying to get the auto's I like right now (rifle and pistol). Next will be high-power bolt actions, shotguns, revolvers, etc...
If it looks military or SWAT, consider bumping it up on the list, save the hunting stuff for later.
I hope we never have to face this, but some feel that we all ready are, and some of the proposed "anti-terrorist" legislation seems to have completely missed the boat on the real issue and solution. Anyway, if you're on a progressive budget, spend it wisely. And consider using some of the new found monies to join the NRA or support the pro-gun organization of your choice.
Just my $.02
