| Barrel length and patterns: |
| Barrel length and pattern/velocity questions are mostly a matter of complete combustion. So, whether one is getting a complete burn which has peaked in pressure, delivering consistent velocity, depends on length of barrel and powder type. Slow-burning powders, such as Alliant Blue Dot®, will take 26 inches or more for complete combustion. Patterns will be rendered inconsistent by inconsistent velocity, a byproduct of an incomplete burn. The closer we get to 100% of the granules burned predictably, the more consistent the pattern will become.
