Is rattling or grunting best for the rutt?

For the "rut" itself, neither one will work as well as simply being where the does are at. Im guessing your asking about the "prerut" and both will work for you if you use them right. The buck doe ratio has to be close for the rattling to work well, so you may have better luck with grunting but dont overdo it. Depending on where your at, a lot of bucks who have been pressured dont respond well to any calls.Hope I helped some, good luck.

Follow the doe...

rattling and grunting combined with a doe bleat usually the "can" by primos works best
