Calling advice- if you hunt a heavily hunted area or public, keep them in your pocket. If you hunt a lightly pressured area definitely do some grunt sequences every 15-20 minutes right now (pre-breeding). I don't like bleating but that's just me. Rattling, never had much luck either other than small bucks. But get that grunt tube out if you are hunting lightly pressured area for sure. In another 10 days or so the bucks won't much attention to anything unless you smell like an estrous doe.
