Seriously... Sand would be the most economical route, however make sure the sand is 100% dry. Many play type sands are bagged and shipped moist after being exposed to rain. I would prop each bag in an upright position, and cut a slit in each bags top. Opening and allowing it to dry out in a non-humidity area for a few days prior to filling your rustable steel stands.
Lead shot, is not something you really want to play with. Lead dust is even worse! I heard horror stories of fellows that used lead to fill their stands in their listening rooms. Missing the stand, & spilling it all over the carpet. Lead is also non-magnetic, & using a vacuum would agitate the lead dust. I can send you a 16 page EPA brochure on what lead dust can do to a childs still developing mind. So if you have children I would strongly rule out the lead.
So let's talk about the Numero Uno Rule of filling a stand.
1.) No matter what filler is used, if possible due to stand weight, fill stands Outside or in your Garage in case of SPILLS!
A company called Atacama makes a product called "Atabites" which is a high density filler manufactured from steel chippings and designed for the mass loading of speaker stands. This a coarse mix of triangular shaped steel chippings which is a worthy investment to get the best out of the stand and producing better imagery and extra bass control at louder levels of volume. Atabites are available in 19.8lb pour bottles. It is also magnetic so if your funnel slips the Atabites are magnetic for a no loss clean-up.
