Horizontal Stringing Issue - OutdoorEdventure - 05-31-2019
Loads 85-100 gr standard grouping until sub-MOA w/ 15 FPS spread.
Loads 120-125 gr horizontal string but I still find a sub-MOA w/15 FPS spread.
Anyone ever have this issue.

Anyone ever seen this happen or have an explanation of why it strings horizontally instead of vertically until I find the sweet spot?

Shooter shoulder wiggle, trigger finger wiggle, palm push/wiggle. My experience (not a marksman but stay at Holiday Inn Express!! lol) is most horizontal movement is from the shooter/shooter position.
Erratic, triangular, scatter prints are load charge/accuracy or something is loose.
One-dimensional patterns are a different story.

I have watched your videos and seen your comments here, there and yonder. So, I believe you are a very capable shooter as well.
I have a couple of thoughts but will throw out what I think from what I see in your video.
Reposition after every shot. If the recoil is walking the gun on your shoulder it will string.
I have coached a few shooters off and on when they ask me. My analogy is make each shot your first shot. If it doesnt feel right, put everything down, start over and make it your first shot.
I myself absolutely hate shooting for groups. I will stack a few, then one slips out and I let it get in my head.
Something else I see a huge majority of shooters do, they want to blow the center out of the dot,square, diamond etc. WHY??? Doing so you then have a torn up ripped up POI! There is no way you can hold the same when it is gone or torn up. Easy fix, run up, down left or right, just so long as it is in a group who cares where, we can all ways move it.
Some will say I dont want to move my scope. If it wont repeat it is junk and will screw you sooner or later, when being the major question.
I have other thoughts, but I am no great group shooter with the AR platform.
Worse comes to worse, have some one with good skills test drive it.
