Powder Description & Technical Profile
Physically, Winchester 572 is a spherical vs-extruded powder characterized by its small, uniform, flattened ball grains. This grain geometry is a hallmark of the Winchester manufacturing process, designed to maximize bulk density while ensuring that each charge settles identically in the case or hull. Chemically, it is a single-base vs-double-base powder belonging to the double-base category. By incorporating a measured percentage of nitroglycerin into its nitrocellulose base, Winchester 572 achieves the energy density required to drive heavy projectiles or shot columns at competitive velocities while maintaining manageable pressure curves. The grains are finished with advanced deterrent coatings and a graphite glaze to control the ignition rate and eliminate static cling during the reloading process.
The versatility of Winchester 572 is largely due to its carefully tuned pressure curve. Unlike faster target powders that peak rapidly, Winchester 572 provides a sustained gas volume that is ideal for mid-range velocities where consistent work is required throughout the barrel’s length. This makes it particularly effective in the 28-gauge, where maintaining pattern integrity at 1200-1300 FPS is a primary goal. In handgun applications, this same sustained pressure allows for reliable slide cycling in semi-automatics without the “snappy” recoil impulse often found in faster propellants. Furthermore, the modern chemistry used in Winchester 572 ensures that it burns completely even at moderate pressures, which is a significant improvement over legacy powders that often leave “powder ash” in the barrel when not pushed to their maximum limits.

Technical Characteristics
The technical specifications of Winchester 572 highlight its role as a modern, high-density propellant. Its physical properties are optimized for the tight tolerances of modern reloading equipment.
| Feature | Specification |
| Manufacturer | Winchester (Hodgdon Powder Company) |
| Powder Type | Spherical vs-extruded powder (Flattened Ball) |
| Base Type | Single-base vs-double-base powder (Double-Base) |
| Relative Burn Rate Category | Mid-Range |
| Density (g/cc) | 0.845 |
| Primary Application | 28-Gauge and Performance Handgun |
| Grain Shape | Flattened Spherical |
With a density of 0.845 g/cc, Winchester 572 is a relatively “heavy” powder for its volume. This is a significant advantage in cartridges like the 9mm Luger, where internal case capacity is at a premium. The reloader can achieve high velocities with heavy 147-grain bullets without encountering heavily compressed loads, which can lead to bullet “creep” or inconsistent seating depths. In 28-gauge hulls, the high density allows for a compact powder column, providing ample room for the wad and shot charge, which is essential for achieving the perfect fold crimp that keeps shells from leaking in the field.
Temperature Stability & Burn Rate Analysis
In the spectrum of modern propellants, Winchester 572 occupies a versatile mid-range position on the burn rate chart. It is generally situated in the neighborhood of legacy powders like Alliant Unique or Hodgdon Universal, but it offers a more modern chemical profile. Because it is slower-burning than dedicated target powders like Winchester 244, it is much better suited for high-performance loads where a higher velocity ceiling is required. Its burn rate is specifically tuned to generate the necessary gas volume to cycle modern semi-automatic actions reliably while keeping peak pressures within safe SAAMI specifications.
Temperature stability for Winchester 572 is robust, benefiting from the latest advancements in ball powder technology. Historically, double-base ball powders were criticized for velocity shifts in extreme cold or heat; however, Winchester 572 utilizes modern stabilizers that mitigate these effects across a broad operational range. When compared to a highly stable benchmark like Hodgdon CFE Pistol, Winchester 572 maintains very competitive consistency. Compared to a more temperature-sensitive benchmark like older flake-style propellants, Winchester 572 is significantly more predictable, which is vital for competitive shooters who may develop a load in a climate-controlled environment but compete in extreme outdoor conditions. This stability ensures that the shooter’s point of aim and recoil impulse remain constant regardless of the weather.
Powder Comparison
To properly position Winchester 572 on your reloading bench, it is useful to compare it against its primary rivals in the mid-range category.
| Powder | Relative Burn Rate | Density | Primary Application |
| Winchester 244 | Slightly Faster | High | 9mm Luger, 45 ACP Target |
| Hodgdon CFE Pistol | Slightly Slower | High | 9mm Luger, 38 Super |
| Winchester Super Field | Similar | High | 20-Gauge, 40 SW |
| Winchester 231 | Faster | High | 45 ACP, 38 Special |
Compared to Winchester 244, Winchester 572 is a slower-burning option that is better suited for heavy bullets and high-velocity applications where 244 might reach its pressure limit too quickly. When compared to Hodgdon CFE Pistol, Winchester 572 offers a very similar burn rate but is often preferred for 28-gauge shotgun loads where CFE Pistol lacks optimized data. Against Winchester Super Field, Winchester 572 provides a more modern alternative that is specifically designed to be cleaner-burning in small-capacity cases. Finally, compared to the legendary Winchester 231, Winchester 572 is much slower, making it a “step up” in power for those who find that 231 does not provide the velocity they need in cartridges like the 40 SW or 38 Super.
Performance, Metering & Equipment
The metering behavior of Winchester 572 is one of its most cited advantages. Because it is a small, flattened spherical powder, it flows through measures with the fluidity of liquid. On a high-speed progressive press like the Dillon XL 750 or the Hornady Lock-N-Load AP, charge-to-charge consistency is often within 0.1 grains. This surgical precision is vital when loading for competitive shotgunning or precision handgun matches, as it ensures that every round has the exact same velocity and recoil feel. Unlike flake powders that can “bridge” or snag in small powder drops, Winchester 572 drops identically every single time.
For reloaders using automated equipment, the high density and smooth flow of Winchester 572 ensure a clean and efficient workspace. There is very little “powder spray” during the indexing of the shell plate, which keeps the press running longer without needing a teardown for cleaning. Even on a single-stage press, the uniform grain size ensures that the volumetric drop is consistently accurate. This predictability is especially beneficial for the 28-gauge reloader using specialized shotshell presses, where consistent powder drops are the key to maintaining the high pattern efficiency that the small gauge is known for. Its ability to flow through small apertures also makes it an ideal choice for loading smaller-bore handgun rounds where charge holes are tight.
Recommended Cartridges and Applications
While its role in the 28-gauge is its primary claim to fame, the versatility of Winchester 572 makes it a stellar performer in several popular handgun cartridges.
| Cartridge | Primary Application |
| 28-Gauge Shotgun | Competitive Trap and Skeet (3/4 oz) |
| 9mm Luger | High-Velocity Target and Defensive Practice |
| 40 SW | Performance Target and Competition Loads |
| 45 ACP | 230-grain Standard and High-Velocity Loads |
| 38 Special | +P Defensive Practice and Heavy Target |
| 357 Magnum | Mid-Range Target and Plinking Loads |
In the 9mm Luger, Winchester 572 is particularly efficient with 124-grain and 147-grain bullets. It provides enough gas volume to reliably cycle the slide while keeping the pressure within standard SAAMI limits. For the 40 SW, it offers a pressure curve that provides the “snap” needed for duty-style practice but with less felt recoil than faster-burning target powders. In the 357 Magnum, it is an excellent candidate for mid-range plinking loads where a full charge of slow magnum powder is unnecessary and inefficient.
Bullets
Pairing Winchester 572 with the correct bullets allows the reloader to fully utilize the powder’s sustained pressure curve. Because it is a mid-range propellant, it works best with jacketed or high-quality plated projectiles.
| Bullet Brand/Model | Recommended Weight | Application |
| Nosler Custom Competition | 124-147 Grains | 9mm Precision Target |
| Sierra Sports Master | 185-230 Grains | 45 ACP Target and Defense |
| Hornady Match | 158 Grains | 38 Special Heavy Target |
| Lead/Coated Cast | 180 Grains | 40 SW High-Volume Competition |
For 9mm shooters, the Nosler Custom Competition 124-grain bullet over a mid-range charge of Winchester 572 creates a very accurate and clean-shooting load. In 45 ACP, the Sierra Sports Master 230-grain FMJ is a perfect match, providing the classic weight and feel that shooters expect from the platform. The “cool-burning” nature of Winchester 572 is also beneficial for shooters using polymer-coated bullets, as it is less likely to vaporize the coating and cause excessive smoke compared to hotter-burning propellants.
Primers
Consistent ignition is the foundation of accuracy for any mid-range ball powder. Winchester 572 is designed to ignite reliably with standard primers, but because it is a double-base spherical powder, using a quality primer with a consistent cup and mix is vital for keeping velocity spreads tight. In shotshell loading, the primer choice is a fundamental part of the recipe and should never be swapped without consulting published data. For handgun loads, standard non-magnum primers are typically the best fit.
The energetic flash of a quality primer ensures that the deterrent-coated grains of Winchester 572 begin burning simultaneously, resulting in the low standard deviations (SD) that precision shooters crave. Below are the recommended primer pairings for various Winchester 572 applications:
- Winchester WSP – Small Pistol (Standard for 9mm Luger)
- CCI 500 – Small Pistol (Excellent for high-volume practice)
- Federal 100 – Small Pistol (Highly sensitive for light striker springs)
- Winchester WLP – Large Pistol (Standard for 45 ACP / 44 Special)
- CCI 300 – Large Pistol (Uniform and consistent)
- Federal 150 – Large Pistol (Highly consistent ignition)
- Winchester W209 – Standard 28-Gauge Shotshell Ignition
- CCI 209 – Standard Shotshell Alternative
- Fiocchi Small Pistol – Reliable European option
