Powder charge absolutely has something to do with vertical stringing. No one thing has everything to do with a single symptom of bad grouping.Horizontal grouping is wind, a 150 grain 308 bullet moves about 2" at 100 yards in a full value 10 mph wind. I know you said the wind was less than 10 mph but unless you are in a wind tunnel they are not sustained at a given value. You may break one shot at 2mph and the next at 5 mph. Pressure has a direct effect on velocity. Neck tension, seating depth and powder charge variations will more likely give verticle stringing. If this is a hunting load 1 moa should be good enough for ethical ranges.

Been there!Shot is wind less than 10 mph. From a bench with sand bags. Last group on bottom left was sighting a different rifle. But they are in order left to right, top to bottom. Starting lowest charge working to highest. 4 min between shots for barrel to cool. Started with a clean barrel
I've seen 1 m.o.a at 100 turn into 10" at 500.If this is a hunting load 1 moa should be good enough for ethical ranges
We've all been thereI just burnt up 200 bullets and 2 lbs of powder chasing the same thing. Curiosity what is the rifle? I found my problem after 200 rounds
That's funny. I figured it was a joke about being a cowboy who drove a sedan. Just goes to show......something, I guess, not sure what.I am in Sedan Montana. A little place North of Bozeman, MT.
It's a browning hells canyon max long range.I just burnt up 200 bullets and 2 lbs of powder chasing the same thing. Curiosity what is the rifle? I found my problem after 200 rounds
That's the group number and shot. So I couldPersonally I don't know what your markings on target refer to...but I'd be focusing on 6-1,2,3,4 or 8-1,2,3,4
