Mastering Efficiency: Tune Your Airgun to Perfection with SEKHMET Digital Gauges
Hey there, Sekhmet is thrilled to roll out a series of content about electronic gauges that matter to the airgun community. Let's delve into why I ventured into creating this product and what electronic gauges have brought to the table during my decade-long journey with airguns.
In 2013, I got my hands on my first PCP airgun, the Airforce Condor - no regulator, single loaded. Yet, it brought me immense joy. Subsequently, I expanded my collection with more airguns like the AirArms S510, Huben K1, Snowpeak P35, Walther 1250, FX Impact Mk2, AGT Uragan, and many more. The performance and playability of PCP airguns have seen a groundbreaking evolution in recent years, thanks to the collaborative efforts of numerous brands.
In the pursuit of better performance, especially for benchrest competitions, excellent tuning and consistent repeatability are essential. After using various instruments and conducting personal tests, I believe efficiency is the epitome of superior performance. When an airgun's efficiency is high, its accuracy and user experience tend to be better. It results in less noise and vibration, more shots per air fill, and even the ability to drive heavier slugs with a lighter system, allowing players to experience the thrill of larger calibers.
Here, I want to express gratitude to Ted for sharing his expertise with everyone. He optimizes airguns in a way that most people can achieve. You can check out his video here. Ted mentions in the video that judging a gun's optimal configuration can be done by the sound it makes upon firing. However, this method often falls short for airguns with built-in suppressors or in environments where distinguishing sounds is challenging. Hence, the idea of using an electronic pressure gauge to precisely calculate the exhaust volume is what inspired me in creating Sekhmet.
What I aim to do is uncover these patterns and share them with everyone. That's why I developed the feature-rich 28Pro Gauge. Considering many parameters that users can record and calculate themselves, I further introduced the 25Standard Gauge with only a digital display, offering a more cost-effective option.
Here's a visualization graph about efficiency - Pic1:
- α represents gas efficiency: the percentage of compressed air energy converted to the ammo's energy.
- P0 is a regulator pressure if a regulator is present.
- V0 is the gas volume released per shot, which depends on parameters like your set hammer force and transfer port.
However, peak efficiency doesn't necessarily equate to the best accuracy. It's a systemic engineering process. The premise is to first choose the right ammo and barrel parameters based on the shooting scenario, select an airgun according to your budget and preferences, and then find the most suitable settings for your platform.
Ultimately, most users find themselves in a sweet spot within the optimal range of pellet initial velocity. They strive for the best balance of efficiency, regulator pressure, and exhaust volume for pellet optimization - Pic2.
Hope you enjoy this topic! In the upcoming posts, I'll gradually share how to calculate and achieve optimal efficiency. We're planning to launch a user-friendly efficiency calculation tool on our official website to keep your airgun in its prime condition. The underlying model is often more complex, so feel free to discuss anytime.
Please believe that Sekhmet's discoveries are based on extensive research in the PCP airgun field. I've successfully participated in the development of several PCP airguns, achieving considerable accuracy. The content is extensive and will be continuously updated for an extended period. I hope you follow Sekhmet for the latest updates.
