Actually, their Range Rules PDF seems take it one step further:
"No outside ammunition for pistol or tactical rifle use. Personal ammunition is
allowed for precision rifle shooting after it has been inspected"
Bummer. I know that for me personally, nearly every time I (and friends) go a range, we will use up the ammo we brought in and due to the excitement, end up purchasing more on site.
BTW -- new member, first post here because I was googling places to shoot around Boulder Co.
Never got around to checking out Left Hand Canyon before it was closed down, but from what I usually heard about it, it didn't same like a place more responsible shooters tended to gather anyway.
I did, however, check out Green Mountain Family Shooting center about a year ago to sight in my SU16CA. The guy monitoring the rifle lanes was pretty friendly but I recall the lady working there puffing her chest (so to speak) unnecessarily. And yeah, it was pretty loud in there!
If there's a place around Nederland that anybody knows about, I'd rather drive up there than the traffic to the Silver Bullet...
