Had the same problem with a savage LRPV targets looked like this". . . . ."
Went through all the basics....position trigger pull everything you could imagine.
Problem: Handloads were 3 grains TOO light in my 6BR....followed the manuals but the lawyers must have written the weights of powder.
Once I got up to 30 gr. of Varget instead of 27gr. the horizontal stinging was gone. ( I watched the groups close as the powder quantity went up, always looking for signs of high pressure. 30.3 is where I stopped with the very best groups I can shoot.
This came from advice from this site and I worked my way up slowly. I had never really heard of light loads causing this so if this is what you are shooting........

With my rifle, allowing for my ineptitude, it appears that load plays a large factor. During load workup I've noticed that groups will go from "large and round" to little vertical spread with horizontal stringing, with a few diagonal strings in between. Then all of a sudden there comes a nice tight round group. When the load increases from this point it starts repeating the horizontal, diagonal, scatter again.

Now that's just my rifle.

when I ladder test I get just vertical.

You should throw seating depths into the mix

Basic rule of thumb on that issue.
Too close/far into the lands creates horizontal. Back out slowly.
The opposite holds true for vertical.

Just generally speaking, its not carved in stone and occasionally is reversed or not a factor at all.

I was looking for this information tonight. Glad to see these archives still here. This makes sense to me .

Tune, wind, operator error, improper bag or bag setup.

The biggest thing I see when it comes to fighting horizontal is powder. When I tune a rifle that wants to shoot wide all the time I know I have to switch to a different powder. It can not be tuned out. RL33 comes to mind as a wide powder in some barrels. The competition shooters wont see this usually since we already know what powders the cartridge will shoot. Now if this is something like a ppc or br case and your shooting a common powder then assuming theres no problems in the rifle I would adjust seating depth but this is for minor stringing. If its bad I would check out the rifle and scope.

parallax/cheek weld/ or eye placement?

Did some of those old articles say seating depth for horizontal and powder for vertical? This is what I always kept in the back of my head.

I've experienced horizontal stringing when shooting off a lead sled. Switched to bags and problem went away.
