Goals: .22LR at 50yds, 5.56 (14.5") at 100yds, 5.56 (18") at 50yds
Environment: Muggy and buggy. At start, no wind and light rain, by end, 5 MPH S and no rain. Overcast.
Equipment:
.22lr, sling, eley edge, VO 1-6x (3x)
5.56 (14.5"), sling, xm193, eotech (w/3x)
5.56 (18"), Black Hills 77gr SMK (BH77), L&S 3.5-10x TMR (3.5x)
Activity:
.22LR - decided to keep zero of .22LR at 50yds. If I was shooting at a rat (tree or ground) or a rabbit, etc. 30yds is a more likely engagement distance, but 50yds, might be the extreme and better to hold down in these situations than up I think.
G01 - 2rds - 50yds - 7+7 avg 7
I decided I was aiming too far to the right. No adjustment.
G02 - 3rds - 50yds - 10+9+6 avg 8.33
The high right round was an IBF (inadvertant bump fire) which hasn't happened on this rifle in almost a year, since I put milspec lower on it. Trigger finger too light.
G03 - 5rds - 50yds - 10+9+9+7+6 avg 8.2
2 rds right and high ... is that aiming issue? trigger control issue? breathing issue? My guess is the rifle is zeroed, just not the shoorter

. This will give me something to work on. "Aim for the center of the wobble" as KSE would say!

5.56 (18") - this is first time ever shooting this rifle. Had no idea what to expect so started at 10yds.
G11.1 - 1rd - 10yds
low and left, cranked up 8 clicks and right 8 clicks (1 click = 0.5 MOA)
G11.2 - 1rd - 10yds
low and left, cranked up 10 clicks and right 10 clicks
G11.3 - 1rd - 10yds
low and left, cranked up 4 clicks and right 8 clicks
G11.4 - 2rds - 10yds - 10+10 avg 10
decided to go to 50yds
G12.1 - 1rd - 50yds
waaay high, cranked down 4 clicks
G12.2 - 1rd - 50yds
cranked down 4 clicks
G12.3 - 1rd - 50yds
cranked down 4 clicks
G12.4 - 1rd - 50yds
cranked down 4 clicks and left 1 click
G12.5 - 1rd - 50yds
cranked down 4 clicks and right 1 click
G12.6 - 1rd - 50yds
Finally in the ball park. I had 2 feed issues with the 2nd and third rounds. None after that. Will try some more cleaning.

5.56 (14.5") - trying to crank the EOTECH down for 100yds (from 50yds) so tried 2 clicks down.
G31 - 4rds - 100yds 5+5+5+0 avg 4.75
2 clicks not enough! Tried 4 more clicks down and 1 right.
G32 - 4rds - 100yds 7+7+6+6 avg 6.5
too many clicks down and right! Went 2 clicks up and 1 click left.
G33 - 4rds - 100yds 8+8+7+7 avg 7.5
elevation good, windage probably is too, I guess I am having aiming issue.
G41 - 4rds - 100yds 10+10+8+8 avg 9
G42 - 3rds = 100yds 10+8+8 avg 8.5
Summary/Results:
.22LR - seemed to have intermittant "high/right" problem. Want to do more 50yds day time shooting to investigate further. I think I will switch to whie paper targets with black dot centers and crank up magnification to 6x. I should then be able to see the holes, unless I hit the black dot.
5.56 (18") will try cleaning to see if I can adjust the feed issues. Also will check trigger screws to make sure they are tight. This lower had been on the 5.56(14.5") and did not have issues if I stuck to FLC or BH ammo. I stopped after 11 rounds as that was all I took to the field.
5.56 (14.5") Given that I can only see the top half of the target at 100yds, perhaps the spread of impact is ok, though I suspect I can do better, given 3 tens out of last 7 rds. If I get lucky that often, I want to try to get lucky a little more often!
I am down to 20yds xm193, ordered more Friday. I have plenty of BH77 so I can do some more with 5.56(18) and I have plenty of FLC 62gr, but I don't shoot that, just leave it in the cans. And I have plenty of eley edge.
I tried to co-witness the visible laser on the 5.56 (14.5) to the EOTECH, but the laser would not come on, so I'm guessing I have to switch the batteries. I was not left on! So I am surprised it needs to batteries so soon.
