The purpose of this video is to display data collected from the use of a DSB Fabrication tuner. This is a first in a series on the effectiveness of tuners. Results show that the tuner can reliably have a "best tune" and a "worst tune." Results demonstrate that the tuner can function to "regain" the best tune when atmospheric factors, specifically station pressure, put a well-tuned rifle out of tune. The method to utilize a tuner to effectively find the best tune and regain the best tune when lost include:
- Effective load development while the tuner is fully turned towards the action
- Observing and recording atmospheric data including station pressure
- Conducting an analysis of group shape, point of impact, and size along several tuner settings
- Selecting the "best tune" based on the pattern of group shapes, point of impact, and size along a "sine wave" analysis
- Placing the tuner setting at the "best tune"
- Turn the tuner to regain the tune when the tune is lost due to atmospheric conditions
