I use a combination of calls. I think the key is to sound like you have a few cows in your area. I use two sceery game calls and a hoochie mama. The mini sceery is my favorite. I make it sound like a few cows as I approach, then I let a bugle go to get the bulls thinking thers a bull in the way.. I use two bugles,, primos pack bugle and primos baffle bugle. Give sceery a try I think you will be impressed.
