A bullet weight worm is a crucial component in bass fishing, especially when using soft plastic baits. These weights are designed to slide freely down the line, allowing the bait to sink through the water column and penetrate vegetation. They come in various sizes and shapes, such as cylindrical or egg-shaped, and are made from lead. The choice of weight depends on factors like depth, cover, and the type of fish being targeted. For example, a Texas rig is a common setup that uses a bullet weight to effectively fish in shallow to deep water.
