Truth, I tried rattling for 15+ years granted not every time I went out but enough to say so, the area I hunt has a healthybuck population so I couldnt' believe I couldn't get it to work. I always used small horns and by that I mena a set that was 100-115" 8 point, last season I grabbed a mixed set of big maybe 140+ sheds I had, no lie the first morning I cracked them I had a 3 1/2 come running in before I finished the sequence, I rattled up 3 more bucks that day and had luck the rest of the season maybe coincedence but I doubt it. My advice, small ones may work, but bigger are better, I will garauntee you that.
