During a recent chronograph session with my Oehler 35P I noticed an approx. drop in velocity between the 1st and 2nd trap of 2 fps. The distance between the two traps is 2ft. That translates into a velocity drop of 300 fps over 100 yards. Does that sound reasonable?
Pellet velocity after 100 yards?

Speed drop is not linear by distance... The drag slowing down a pellet is more pronounced at higher velocities, and reduced at lower velocities. For those who are super into this topic, they will well you the Ballistic Coefficient of a specific pellet changes with speed. Programs like "chair gun" are not bad about mapping the velocity change (and drop) over distance. The greatest speed drop is seen in the first few feet.. The speed drop becomes less with distance. However, the vertical drop accelerates with distance as it is a summing function.
