What is Superformance?
Superformance powder has earned a strong reputation among reloaders for its ability to unlock impressive velocities and deliver exceptional performance in a variety of rifle cartridges. Its unique formulation often leads to flatter trajectories, reduced wind drift, and the potential for tighter groups. This article serves as a comprehensive guide for individuals interested in harnessing the power of Superformance powder, offering valuable insights into load data, safe reloading practices, and tips for achieving optimal performance in your rifle. Mastering this powder can significantly elevate your reloading experience, enabling you to create custom ammunition tailored to your specific needs and rifle.
Benefits of Using Superformance
At its core, Superformance powder is a spherical, double-base propellant. This means it’s manufactured with spherical grains and uses a combination of propellants for enhanced performance. This blend allows for a faster, more efficient burn, leading to higher velocities compared to many other propellants when used within a carefully managed load. This characteristic makes Superformance particularly attractive to those seeking to maximize the ballistic potential of their rifles.
One of the primary benefits of using Superformance powder is its capacity to boost muzzle velocity. This, in turn, translates to a flatter trajectory, allowing for greater accuracy at extended ranges. A flatter trajectory means a bullet drops less over distance, making it easier to accurately engage targets without having to make significant elevation adjustments. The high energy density of the powder helps it to efficiently propel the projectile, reaching its intended target with more speed and consistent power. This can be a significant advantage in both hunting and competitive shooting scenarios.
Furthermore, this powder often performs consistently across a range of weather conditions. While all powders are affected by temperature, Superformance is known for its relative stability, providing more reliable performance when conditions shift. This means reloaders can maintain a consistent point of impact regardless of the season or environmental factors, a crucial element for hunting and long-range shooting.
Potential Drawbacks
It is important to address some important considerations when using Superformance powder. Due to its fast-burning nature, the potential for elevated chamber pressures is greater than some other powders. This highlights the absolute necessity of adhering strictly to published load data from reputable sources. Never exceed the maximum recommended powder charge, and always pay close attention to pressure signs as you develop your loads.
Another aspect to consider is the potential for increased barrel wear. The high velocities generated by Superformance can put more stress on the barrel, leading to accelerated erosion. Proper load development, using appropriate bullet weights, and regular barrel maintenance are crucial to mitigate this potential. Finally, note that Superformance is not a universal solution. It may not be the optimal choice for all cartridges or bullet weights. Careful research and experimentation, always guided by published load data, are essential.

Interpreting Pressure Signs and Adjusting Loads
Recognizing Pressure Signs
When working with Superformance powder, it’s crucial to be vigilant in recognizing and interpreting pressure signs. Excessive pressure can lead to dangerous situations, including equipment failure or even injury. The most common pressure signs include flattened primers. A primer that is significantly flattened against the bolt face compared to a fired primer at the starting load may indicate excessive pressure.
Cratered primers are another sign to look for. This is where the primer has a raised area or crater around the firing pin indent. This can occur when the primer cup is driven back against the firing pin hole due to the pressure. Difficult bolt lift is another critical indicator. If you experience increased resistance or difficulty in lifting the bolt after firing a round, it may indicate excessive pressure. This may happen if the case has expanded too much during firing and become difficult to extract.
Sticky extraction is another possible sign of high pressure. This is when the case sticks in the chamber and requires additional force to extract it. Furthermore, examine the brass after firing, paying close attention to things like head separation, bulged cases, or any other unusual indicators. If you observe any of these signs, immediately reduce the powder charge and reevaluate your load.
Adjusting Loads
Always start with the starting load recommended in the published data. Gradually increase the powder charge in small increments, typically around one to two grains, while monitoring for pressure signs. After each increment, inspect the spent cases, and observe how the firearm operates. The most important aspect to remember is that this must be done slowly.
A chronograph is an invaluable tool for verifying the velocity and consistency of your loads. It allows you to measure the muzzle velocity of your rounds, providing an objective measure of performance. Consistent velocities are a key indicator of a stable and accurate load.
