I took a load out to test my Douglas barrel on my mk12. I’ve never seen vertical stringing like this. The two groups are 100 yards. The single group is 200. 1:7 twist with 73 eldm and 8208. What could be causing this? I felt solid on all the shots

It’s tight in the mount and tried a different load all together and it was a typical group pattern
You've basically answered your own question, the load is no good if another load shot decent.

Is this an indication I’m close to somthing? Like need to raise or lower a couple grains?

I was also going to suggest your scope rings or base might be loose. But after closer examination, your horizontal spread seems tight. I think the problem is you aren't using the right targets. Order a few of these and you are set.
Lol, an inch and a half vertical does not constitute being close. But yes, do add or subtract some powder, if you give your case and charge, someone here can dial you in. If your scope rings were loose, your horizontal dispersion would not be so good either.
