Thread: Wind in the Mountains

For my on interest I had a play on a Ballistic programme, I entered in some numbers purely to generate some info to compare my thoughts on bullet weight playing no role in beating the wind.

I used these figures for below:

Using a 300grain 0.338 bullet with a BC of 0.66 and a velocity of 2820fps

1000 -215.8 -20.6 21.5 2.1 2268.9 2.08 4571.4 1.186 0 0



And this time using a 160grain .284 bullet with a BC of 0.66 and a velocity of 2820fps

1000 -215.8 -20.6 21.5 2.1 2268.9 2.08 1828.6 1.186 0 0


Both exactly the same, bar the energy figures. Velocity, drop, drift etc are all the same, so from my reckoning bullet weight has nothing to add as far as beating the wind goes, its simply comes down to BC & velocity (time in flight).

What's wrong with humble pie? Having someone kick you reasonably out of the comfort zone is a very effective way of learning. Just making mistakes without understanding why does the opposite.

I would suggest to start shooting without your Kestrels and leave ballistic computers in the study room. Stick to the basic and free handout I've given and you'll see the pattern for mountain shooting soon enough.
Film where we shoot in windy mountains. (The lessons given here was more detailed and handson than the basic course on NZ). It doesn't really tell how as the aim here was to show factory gear.



Other than that, KiwiGreg pretty much said it. Re-read his post so I don't have to re-type.
