Looking at your results, it looks like you might have had some gusts in those 17 mph winds.
You didn't say if you were using wind flags.
Reading the wind is critical when you shoot at 100 yards or longer because the .22LR is going so slow that a 5 mph wind can move a bullet up to 1/2 inch.
Also, at temperatures around 40 to 45 degrees, you will probably begin to see a drop (maybe one out of 5) from the primer and or powder not igniting consistently. Keep your ammo in an inner pocket before you load it in a magazine.
