I purchased a rattle bag this season. It sounds good to me, but since Im a novice with it, who the heck knows if it really sounds good.

Anyhow, I was wondering how long I should rattle:

1) before I pause before starting up again
2) how long I rattle in total

I used the bag a few times during the rut this season during slow periods and had no success. Any info you all could share would be helpful.

Thanks
