I could throw another spanner in the works for you here too.

BC can change by a noticeable amount by increasing or decreasing your muzzle velocity.

It seems counter intuitive that if you reduced your muzzle velocity by 20fps you could end up with a pellet that takes less wind.

All of this is a complete waste of your time however

A lot of the time when a shooter misses the kill and there's enough wind on the course to take you out of kill - the miss will be blamed on 'The Wind'. These same shooters will wonder how the hell the likes of Calps, Taylor, Ozzy, Berty, Conor etc managed to only miss 1 target on the whole course when you missed a dozen (all because of 'The Wind')

You'll quite often hear the same people wonder whether those elite shooters have some sort of sixth sense about the wind or are in league with the devil and are able to see changes in the wind before they happen and compensate for them.

Who knows, that might be true.. but something that all of those shooters have in common as well is that when it isn't windy, they'll also still bloody good shooters with awesome technique.

The long and the short of it is - you 'might' gain a very very slight advantage shooting in the wind by experimenting with different pellets and leaf blowers BUT... you will gain a much much larger advantage in the wind by finding a good batch of pellets (whatever weight) and spend a lot of time practicing your technique.

The more accurate and consistent you are when it's not windy, the better chance you have of putting a pellet in the kill zone when it is windy.

Have a read of this thread
Which was designed to give you a practical example of why this is true.

Try two things in the Wind Training application :

Use a BC of 0.031, MV of 710 - ranging accuracy of +/- 2 and put in an average group size of 30mm at 55 yards, then go and shoot one of the courses in the application - 'Mendip' for example. (this emulates shooting a 10.3 grain pellet with reasonable accuracy and about average range finding ability).

Now go back and change the settings to these :
BC - 0.023, MV 780, ranging accuracy +/- 1.5 and average group size of 20mm at 55 yards and then shoot 'Mendip' again.

Sounds convoluted, but it's a lot less hassle than getting out leaf blowers and ballistic calculators and if you've done it right - you should come to the conclusions that TOOL's advice is bang on the money.

Find a pellet that suits your gun, buy a lot of them and practice your technique. There are no shortcuts (don't think you're the first engineer in the last 30 years of FT to think there is)
