There is a new article on H.A.M.... It deals with work by Miles Morris on possible drag models for typical airgun slugs....

It is theoretical in nature, but provides some insight into the anomalous results we are seeing compared to the commonly used G1 drag model....

rsterne:
I have just published a new article in H.A.M.... I discusses the difference in some of the Drag Models used in airguns, and why we need a new one!....

Using the G1 model will lead to incorrect trajectory and wind drift predictions for our slugs, which are capable of being used at higher velocities than is optimum for pellets....
