My Vaquero must be a little different than others. I usually use very little disc. When i hit a target I thumb it up and pull tabs almost always give a crackle ,double blip , somewhere around foil and nickle. I have never heard another person report this.The pull tab itself will not disc out until later . There are always exceptions and I usually dig them anyhow but they are one of the easier things that i can ID with a Vaq and stock coil.
