A wind condition?

Wind is really wierd when coming straight at you or straight away. The twist on the bullet affects how the wind acts on the bullet therefore you don't really get a straight up or straight down result. One time you do get straight up and straight down is when shooting on partly cloudy days. When most of your group is fired either in sun or under cloud cover, then that changes the verticle is usually a bullet hole or more.
This table may help, I don't use it, but it gives an idea of dirrection to expect.

Well, Maybe
At Tomball, we say there is "built in verticle", especially on the right side where there is a big hump in the middle of the range. If your Rifle is not tuned to the hilt, life can get pretty difficult down there. That being said, I think Gene Bukys shot about a "eighteen" agg down there last Saturday Morning. Didn't seem to bother him that much.
There is certainly built in verticle in reversals. Most of my 6PPC's will exibit at least a bullet holes worth when shooting in a L-R R-L reversal. It does seem that the L-R drives the bullets further down than the R-L drives them up.
Many say that a straight head or tail wind will do the same. Once again, though, it seems that if the Rifle has a really good tune, the affect is greatly diminished.
In matches, most experienced shooters will try to get a handle on what is happening that day. It seems that sometimes what should happen, does not. I swear there are times when the Rifle will shoot great in a predominant condition, say L-R, but real crummy in the R-L.
When shooting at a level of accuracy that we have to attain, it seems that some of the generally accepted rules of bullet flight just don't apply. You sometimes have to figure things out on the spot. Hopefully, before you dig to big of a hole. Just saying "do this when this happens, or that when that happens", will probably get you somewhere in the middle of the pack...........jackie

I wouldn't place any faith in a table. You're wise not to use one.
We had wind coming from the 10 and 11 o'clock positions in Austin on Sunday. Our range points dead North in the 12 position which orients with the table. Instead of bullets impacting at the lower right side of the table in the indicated 10 and 11 positions they were impacting high and to the the right in what would be considered the 1 and 2 o'clock positions on a normal clock. A long ways from the table's indicated impact positions.
I only use sighters to tell me what's taking place. In my humble opinion those tables are worthless.

I don't think that table is useless Art.

On second thought, you're absolutely correct. If it were laminated, it could be used as a coaster. So ... it could be useful. Art

If you are shooting much on terraced ranges, you might take a look at what Rick Graham is up to these days. We seem to have a lot of terraced ranges around here. Rick has a pretty good idea that looks like it will help spot conditions on those ranges that can cause some vertical dismay..........I'm optomistic that his new ?flag? can help me something like it did him.

John,
I am fairley new to the game. However I have found wind with a combination of mirage can cause vertical. Especially when the mirage out weighs the wind. We had a condition this past weekend were the day started off , typical, 40F wind /switch 1:00 -11:00 eventually a drop in velocity combined with and brighter / warming condition sent a bubble of goo across the range. Wind flags would indicate a 4:00 light hold to float the shots onto the dot. 1:00 o'clock wind. The bubble, mirage, would start running from 9 -3 even though flags were still 1:00. This ended up with a 7-8:00 o'clock OR 4:00 low scratch ten ? I couldn't bring myself to attempt a record shot with wind running at 11:00. Sighter proved totally unpredictable vertical . I focused on a few flags and shot the direction of the mirage. Flags were there to show velocity and a 1:00 direction. Wind Pick up and steady 1:00 right to left mirage, dot on dot, send it. It took a blown third match to figure that out, no lost points, thank the wind god's . Ended up with 2 no hold and 1 over hold, line breakers on both ends of the 10 ring. There again, when that much is going on, who really knows what happened? All I know is this saved my day and did last season on a few occasions too. The wind charts are good to help understand what should happen and why, not really what will happen all the time. Call your shot, hold accordingly to the chart and send it to the sighter. Then hold/click to what that tells you. I am at the point were I will rely on the mirage run and a few close flags over the total line of flags and a probe until The wreck occurs. I dont own a probe, but a few fellow shooters are sharing, I just have to peek every now and then. Probe will not indicate direction of mirage. Just Something to try if practicing in a mirage.
