Why, Roger, do you make the assumption that ammo is "a wasting asset?" Why do you assume ti will get used? If I had X amount of ammo on Day1, why would I not have it on day X + n??? Ammunition expenditure rate varies as a direct function of the need to expend it and context in which it is to be expended.
For those of us with exceptional combat handgun proficiency, my use of Air-Soft pellets in force-on-force scenarios is all I need to maintain proficiency. With respect to other firearms some folks have, they have sufficient stock already on hand so that even the expenditure of some requisite # of rounds they have already determined to be needed for maintaining proficiency at, say 600 to 1000 yards, will hardly put a dent in their stores.
You make the mistaken assumption that all firearms owners are out on the range everyday shooting up their supply. Not true. You also may be making the unwarranted assumption that shooting up mega #'s of rounds is requisite to maintaining proficiency. Not true. So, ban or control, whatever. Right, we sure do control driving with driver's licenses HAHA. Ask the LEO in the area I provide consultation to. The, to use the politically correct language, "undocumented immigrants" are driving amok, w/o driver's licenses - now that's real control 😀 Indeed, such failed efforts typically lead to a ban. Banning is de facto control, nicht wahr? The forthcoming and again impotent hi-cap magazine ban, "assault" (sic) weapon ban, will have the same effect as the previous one. NONE AT ALL.
Happy shooting 🙂
