Wind

[Irish]

Hi all,

Just a quick question....how much effect will wind have on a group at 100 yards? (140 AccuBond in 270)

How much wind?

About .5" at 100 yd with a 10 mph cross wind.

and gusting winds can open up your group too.

Irish,

Practice makes perfect when shooting in the wind! Gusts will definitely open up a group. Unfortunately one of the spots where I usually hunt always seems to have a 30-40 knot wind!!! If hunting try and stalk directly into the wind, sometimes it's the only choice, unless there is steady side wind then you can account for the wind drift after some practice.

I think it's amazing how wind, humidity and altitude can affect a bullets performance. But.... rain seems to have no effect due in part to the shock wave in front of the bullet?? :roll:

I think most Benchrest Shooters will disagree. I lot of times i have saw shooters when their relay would have to shoot in a down pour an no good groups would be shot. When the bullet dead centers a big O raindrop its out of the group.

I also agree that rain will affect a bullets performance.
The last part of my post was intended to be sarcastic in nature.
A while back I posted a question abought sighting in while raining and most of the replies were like the last part of my earlier post. Hence the rolling eyes :roll:

Shooting in high winds is an art. Growing up in Wyoming, I can tell you it takes practice, practice, practice, a good wind gage, and a good balistics table. At 100 yards, for hunting purposes, it's not that big a deal. A 30 mph crosswing will throw you 140gr AB about 2 inches off. At 300 yards, it's close to 20 inches, and at 500 years, it's close to 50 inches. Sounds like you already have a windy place. I'd suggest setting up your targets at 50 yard increments, out as far as you are comfortable shooting, and trying out your favorite load. But bring several boxes of shells....you'll need them.
