20 MPH NE
Goals: 5.56(18) 500yds with 55gr XM193 FM REMAN
Environment: Cool and snowing. Forecast varies, but snow all day and -7F or so before morning. Wind variable direction but usually the snow is coming down sideways.

Equipment: 5.56(18) with B5-25x, atlas, SPW556, kestrel, LRF, buggy
Activity: Two friends from KC threaten to come out tomorrow and go shooting with me. I’m not sure they will make it, given the conditions, but I figure I must prepare.
I think it will be easier if I have them shoot my 5.56(18) and have it setup before hand.
So I setup a 500yds NRA regular 10 point target and a 100yds NRA 10 point target and one of the new shootingsteel7 steel targets.
The 100yd groups was good on elevation but seemed to be a bit to the left The wind could’ve done that, but also possible due to high winds last time, that my zero is off a bit on windage.

Proceeded to 500yds, and fired 5rd group on paper and was low and but straddling the bull. I held 1.25 mils for wind. I could see the wind direction because of the snow fall and it was right to left across the bullet path. The speed was varying between 15 and 22. I could see and hear the variation of the wind.
Then fired 10rd group at the steel and got 6 hits. That isn’t great but it is what it is. In general I could not see the splash of the misses, but finally I did see one just off the left shoulder. I was aiming at the center of the head, as my elevation was hitting a little low and I had been holding between 1.75 and 1.25 mils. Once I saw that miss, I was on target for the rest. The target was at an angle thus reducing the profile width by maybe an inch. These targets say they are 12x24 inches.

My zero stop is set at 500yds, so I held down 3 mils at 100yds and no hold for elevation at 500yds. The 55gr is about 1/10th of a mil low at 500yds.

So, if I call the wind and the visitors can get decent eye relief and diopter settings, then they should get some hits at least.
(update - visitors cancelled - they missed a great day for shooting today!)
