Righto. I have to eat a bit of humble pie for overlooking/dismissing something so obvious.
Wind😆
Our range is situated in a draw at the foot of some decent hills.
I shot this project roughly at the same time of day everytime on fine days and did not take into account the katabatic wind coming around a ridge adjacent to our range.
It appears to come down the draw into your face but it is actually a full value wind of 4.5-6mph most of the day until it warms up a bit, especially from late summer till now.
I have discussed my frustration with a longtime hunting mate and avid shooter who alerted me to it and when tested over the last few days it appears he was spot on.
I also smacked a drink can full of water today, dead center at 250m with only elevation dialed in over a flatter area with a tail wind of 1-2mph.
A 4.5 mph full value wind on my Calc at 200 is a 1.2" drift.
The mpi of the last 4 shots fired is 1.2" left of zero😆
I feel pretty stupid for overlooking the wind component but I am chuffed I have gotten to the bottom of it and it is not an equipment issue which I was leaning towards.
I should have picked it up when I was shooting my AR at the same range and the group was a smidgen further left again but I put it down to sight picture with a red dot almost blotting the target out.
I will keep the experiment going as I have 5 more shots to do but it will try to shoot it later in the day if possible when there is less wind or dial the half minute required.
