I like to wait 2-3weeks before callin the same spot. In the to put about 1/4 mile between stands. I have called from the same butt print in the dirt before with success. When I do go back I try to use a diffrent sound. If u use the same sound I personally think they can relate it to when they last herd it & it went bang & they lost there buddy. If I do use the same sound, I try to wait as long as possible before I do, month,month & a half.
