hmr shots high and low??

[snipers eye]

hi all,was out today to do some groups,set up 1" circle at 100 yrds, yes it was breezy gusty,,but not to bad,about 15 mph,the shots were either high or low by between 1-2 " ,all shot were in line with the bull,but were high and low,so,would wind do that?or does the wind only blow the bullet left or right?

Was the wind from the side? Depending on the spin direction wind can make a bullet go high or low. The rifling grooves in the bullet can encourage the bullet to walk up or down against the wind coming from the side.

the wind was side to side one minute and an odd gust in my face,so it seems it was all around me.i was in an old sand quarry,wind was not that strong,like i said the shots were in line with bull,just either high or low,thanks for your input

Is it a new setup? Is it possible the scopes faulty or maybe you was mounting the rifle inconsistently? I have my scope set as low as physically possible or shoot rubbish, can't stand med/high mounts without some sort of comb raiser in place.

Wind can lift or depress a bullet as it follows the contour of the land (imagine wind flowing like water in a river if you like) cast your fly square to the rivers flow and it will swing across the current down stream(just like a bullet in the same 3 o'clock & 9 o'clock wind drifting you sideways situation). were the river meets a big rock etc. the river will boil up and lift you fly in the water (this is an uplifting wind) under a waterfall (a depressing one). Now to the shooting if you shoot from the top of a hill with the wind at 12 o'clock it will lift your bullet, you shoot parallel to the edge of that hill top with the lifted wind acting on the bullet longer at its peak upward lift - it will lift it more as well as drifting it sideways markedly so. This will also work in reverse if you have a depressing wind flowing a contour.

The other effect on bullets and wind relates to twist direction, wind can get under a twist and lift it up more. Now back to the river, channels or as anglers term them crease lines or rip lines exist in wind as in water (that's another point, it might seem still of any wind were you are but it might not be still all the way to target and it will hardly ever bee the same speed all the way to target) and back eddies do also exist in wind just to add to things. In short read the ground to read the wind it reacts to contours and obstructions

 

The HMR is a good rifle to learn wind on because once you get to 100 yards there will hardly be a day without enough wind to move you some place.

Sounds like fishing the fly through a boil, having up and down forces all in a small area over a hole in the river bed (the hole being a quarry, the river being the wind)

thanks for the good explanation,makes sense,i think i wont try again until there is absolutely no wind,then see how it goes,i just thought it a bit strange,i had a high and low pattern all in line
