[QUOTE="Mikecr, post: 356315, member: 1521"] It's more dynamic stability(Sd) than gyroscopic(Sg). Sg climbs downrange, whereas Sd can decay. I don't know that it can be predicted.. It may very well be how the BC was reached. For instance if shape was used over weight, there might be dynamic stability issues not observed if weight were used over shape. There are bullets marketed that are known to have dynamic stability issues(like the 168 SMK's), but perform well for intended use/ranges. [/QUOTE]
