Horizontal Stringing Causes?
- Thread starter double g

wind and operator error.
that would definetly not help either. 
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.
Now that's just my rifle.
when I ladder test I get just vertical.

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

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.
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.
