I tried rattleing for the first time this year with limited success. Just wondering if anyone would like to share their secret techniques or are there any secrets to it .

When you are rattling you want to try to make as much natural noise as possible kick leaves, beat the ground, and if your in brush make a lot of noise with it add agrunt in there every now and then. Make sure you really rattle not just clank the horn together a little bit but do it hard. If you've ever seen two bucks fight they make a lot of noise. So make some noise.

This link should help you out, good article.
