[QUOTE="Michael Courtney, post: 591440, member: 28191"] The latest issue of Precision Shooting (Jan 2012) includes an article that I co-authored with Don Miller where we present an improved stability formula that more accurately predicts stability for plastic tipped bullets. The stability formula that Don published several years ago works well for bullets of near uniform density, but tended to underestimate stability of plastic tipped bullets owing to the much lighter density of the plastic. Consequently, the original twist formula might have caused shooters to lean away from a given plastic tipped bullet design for rifles twist rates and conditions where they are fully stabilized. It was a pleasure working with Don in the development and testing of the new formula, and we expect that the new formula will prove useful. [/QUOTE]
