Sorry, I fat-fingered that. It is 200 (making sure I hit the right number on my keyboard) [two hundred] yards of an inhabited dwelling or feedlot. And it is specific to rifle. A land owner or lease holder may hunt (shoot) within 200 yards of a dwelling or feedlot on his or her own (leased) property.
The 200 yard rule is a regulation established by the Game & Parks under Title 163 of the Nebraska State Administrative Code.
Now, because it is a Game & Parks reg, it may or may not apply to a range.
This one?
"Permission is required to hunt on private land. It is unlawful to hunt with a rifle within 200 yards of an occupied dwelling or feedlot without specific permission for that purpose or within 100 yards using other methods."

Because there is an interesting statement there about 1) without specific permission, and 2) "hunt" instead of "shoot" (because those definitely aren't the same thing, and you could easily prove that).
Personally, I wouldn't think that would have any bearing on range requirements. (NOT a lawyer.) However, since you aren't hunting, hunting regulations wouldn't apply, IMO.
...as an addendum, the snowmobile rule really is ridiculous.
