Speer Jacketed Handgun Bullets .38/.357 Mag .357" 128 Gr Uchp 450/Ct
Speer Jacketed Handgun Bullets in .38/.357 Mag are engineered for reloaders who demand consistency and reliability from their ammunition components. These 128-grain UCHP (Ultra-Copper Hollow Point) projectiles are built with Speer's Uni-Cor jacket technology, which ensures a perfectly uniform copper jacket on every round. That uniformity translates directly to shot-to-shot consistency—tighter groups, more predictable ballistics, and less frustration at the bench or on the range. Whether you're loading for target practice, competition, or self-defense training, a 450-count box gives you enough bullets to develop and test loads without constant restocking.
The .357" diameter and 128-grain weight put these bullets in the mid-range for .38 Special and .357 Magnum loads, offering a practical balance between velocity and recoil. The hollow point design provides reliable expansion when needed, while the jacket-to-core bond ensures the bullet stays together under the pressures typical of magnum loads. Speer's reputation for quality control means you're getting bullets that will perform the same way, shot after shot, which is foundational to accurate handloading.
Serious reloaders—whether you're chasing tight groups at the range, loading for competition, or maintaining a self-defense battery—know that bullet consistency matters more than almost anything else in the equation. Speer's Uni-Cor process removes the guesswork. You get a large quantity in one box, so you can focus on what really matters: perfecting your load data and your technique.
