Rattling horns I have never tried, although I have a set. May experiment sometime with them. Grunt tube and doe bleat/grunt I use every year. I normally don't use them if I am seeing deer off and on. If things are real slow, I will try a few rounds of both. I can remember 3 bucks over the years and a couple does that I beleive to this day were responding directly to the call, as it wasn't more than 10 minutes till, and 2 less than 5, that they showed up to be put in the freezer. They do work but I think they can be "over" used at times as in getting too anxious for action. Patience is the key. 4 years ago during ML"firearm" season, I was after an 8 point I had seen during bow season. I had already taken a 6 point during archery season. Another 6 point crossed in back of my tree at about 50 yards and I let him go. Wanted a better look so used the grunt tube and sure enough, here he comes. Ended up taking him with the ML at 25 yards. If I knew then what I know now about my property, he would have walked as I now practice the best QDM that's possible on my place. The last three years I have shot the 3 largest bucks I have ever taken all in sequence. 8 point, 9 point, 9 point. The bar is raised every year for a larger buck. Anyway, YES calls DO work if not over used. Try it and you'll prove it to yourself. There is no substitute for patience though.:chillin:
