@hoople, thanks much, great article. It basically proves what I've written about above… It shows scientifically that there is no benefit  to raising your pellet speed much over 900 FPS for target shooting at 100 yards.  Whodathunk?  

{From the Hard Air Magazine article referenced above:

When you shoot in a crosswind, the pellet drifts sideways, causing your POI to be downwind of your POA. The largest factor governing the magnitude of this drift is the BC.

There are many misconceptions about wind drift, the biggest being that “time to target” is the key [velocity]. That is NOT the case. The wind drift is proportional to the DIFFERENCE in the actual time of flight, compared to what it would be in a vacuum. This is called the “lag time”.

This is a difficult thing to wrap your brain around, and even harder to explain without involved mathematics, so I will leave to you Google it if you don’t believe me. However, it is a fact that we have to deal with when considering the external ballistics of diabolo pellets.

Since the lag time is the key, then how fast the pellet slows down (mostly governed by the BC) is the key.}

So now the big question. Except for shooting slugs (whose BC is much higher than pellets), why are all these shooters working so hard and spending so much money to get their 100 yard target rifles (diabolo pellets) shooting at 950, 975, 1000 fps and beyond? Other than using more air, and making the gun harder to shoot, what's the point???
