Yep it's called "driver error".

My bet is when shooting off of the bench you are sitting off to the side instead of right up square behind the rifle.

This won't make much of a difference with a heavy bench gun but with a sporter weight rifle it can create a lot of torsion throwing the barrel left and right like holding a fishing rod out in front of you and wiggling it left-right.

Square up behind the rifle solidly and make sure you are getting a solid and consistent cheek weld just like you do prone and it should tighten things up considerably.

The Tall Test eliminated scope alignment and cant I use a level on my top turret to verify that I'm shooting level.

Please look at the target and tell me your thoughts. It's at 300 yards and the one to the far right was a fouling cold bore shot. I had some oil left in the bore. I piled most of them together but 2 are at the point of aim.



When shooting at 300 yards the last 100 yard of bullet flight travels through a narrow lane of tall pines. Could this affect anything? I don't think so, but I thought I'd toss it out there.
If you have a considerable cross wind between you and the woods, and you are counting it as a full value wind all the way to the target that will make your windage adjustments be off considerably since the woods creates a windbreak.

If you are shooting with a cross wind figure your wind calculation and then take 1/3 off of the adjustment. Ie if your caluclator tells you 12" wind adjustment take off 4 and call it 8".

My bet though is it's still a matter of how you are driving the rifle.

Re: Is it the Wind or Something I'm Doing?

It's got to be the wind...... I had wind coming from 9 o'clock straight left to right at 3-7mph "variable" today. Shot at 100, 200, and 300. Started at 200 and hit 3" right of POA. With the same form and hold I didn't change anything and shot the 100 yard target and hit 1" high from the 200 yard setting and dead center. I then shot the 300 yard target and hit way right about 7" with the same form and hold. I then dialed for wind about 1.6 MOA "per JBM" and shot 3 more at 300 and they were more centered but horizontally scattered I'm thinking of the variable wind.

I did this same test with my 308 with the same results. I may have been just trying to neglect a light wind, but with the anemometer the light wind is more like 5mph.

I just have a lot to learn. I guess I'm not wasting time, powder, and lead if I'm ever so slowly learning.

The toughest wind conditions for me is the ever changing 3-8mph winds. My experiences have been exactly what you've described when I don't give the variable factor enough respect. The fact you had similar results with 2 different rifles tells you 2 things. One it's not a problem with equipment and two you've got to learn to deal with this variable factor.

Scott the secret to success with a variable wind is to time your shots such that you are firing each time when the wind hits the same speed. Otherwise you are going to find it impossible to shoot a tight group with a cross wind.

I think 7" is alot of drift for 300 yards in a 3-7 mph wind, that is just too much. As I mentioned earlier I would get dialed in 1/2" left at 200 yards when there is NO wind and you have a level attached to the scope. Then shoot at 300 and see what happens. I would bet you will not be seeing 7" of drift in that same 3-7 mph wind...but I could be wrong, again
good luck, gary

1.6MOA at 300yds is just 5.02" so it doesn't account for 7" of error.

What scope are you using?

If you can set up and test at 300 and 500yds with either no wind or a straight on headwind or tail wind and see what it looks like.

I'm still leaning towards a driver error or perhaps scope problem.
