I'm by absolutely no means a calling expert at all. I have, however, rattled in bucks on several occassions. It's not necessary to use a scent with your rattling, but it is necessary to time it correctly. The rut is undoubtedly the best time to rattle. Anytime during your hunt will work, but very early in the morning and late in the evening or when you know the deer are moving are excellent. Listen to some rattling on the internet or TV from people who know what they're doing so you know what to mimic. Think about two bucks duking it out and try to copy the kinds of sounds they would make. If you hunt from the ground, kick some leaves and sticks around to make "background" noise, but keep the visible motions to a minimum because when the deer start coming in, it's usually at a spirited pace. I was just like you last year, trying it out for kicks. I was absolutely thrilled to bring in a forkhorn on my very first attempt one morning. So to answer that question, you will bring any size buck in. It's like two kids getting into a fight on the playground, everyonecrowds around to watch. If you're looking for a big boy though, pay little attention to the youngster who may be roaming around your tree and look carefully into the timber around you. I had a more mature buck sit back out of rangeand watchthe younger one run around underneath my tree. The older boys are smart. NEVER continue to rattle once the deer is within a range where he can figure that there are no deer present and that the sounds are coming from above. Basically, just go for it and you might be suprised at the results. I had fun just calling in a youngster because it really does work and I know I have another weapon in my arsenal if I see a bruiser walking out of range.
