Im noticing the same with Tinks this year. I have usually had some luck using Tinks 69, but this year, three hunts in a row, I put out 2 or 3 scent bombs with 69 in them. used rubber gloves every time I handles them, very careful about the wind, and the whole nine yards. In three hunts in a row, Ive had young bucks by themselves get downwind of a scent bomb, and go on full alert! They have all acted very nervous circling and stomping trying to figure it out, then they leave out stiff legged and tail raised, one even snorted at it. I dont know if I got a bad bottle, but three out of four deer that have smelled it have spooked, and the one that didnt seemed confused by it, and nervous.
