I am not too sure where it came from but at the back of my mind I have the guidance figure of 3 - 4 pellets of sufficient energy as a guide to reliable breaks.
When I am assessing a pattern quality this is the pattern density I look for - but this is purely anecdotal. The dome of an edge on target is obviously a tougher structure to break than the thin underbelly of an overhead target as any trap shooter will testify - hence the need for bigger - higher energy pellets. So what is the relevance of single pellet strike performance – unless it is to test batch to batch consistency of the clay targets. I know we are always grateful for the odd single pellet break but I don't think we should be using this as the standard. How you set up a test rig for a 3 or 4 pellet strike at 30 yards I am not to sure - it would need a bit of thinking about!!
