I cut a pair of pant legs off and sewed one end of the leg up. Then I put a plastic bag inside the pant leg and filled it with kitty litter. The kitty litter was from Wal Mart and cost $2.00 for a 40 lbs. bag. I made 3 and they work well, you can't beat the price.

Thanks for all the help. I cut off some jean legs and bought a bag of play sand and hope to zero in my scope this weekend. Sorry my post was confusing. Yes I have a new scope and just want to zero it in. I apreciate this sight so much, because no mater how domb my questions I always get excelent advice. Thanks again for all the help.
