300WM load devlopment vertical and horizontal stringing?

[fnlights]

So I'm working on my load with Berger 205's, H1000, CCI250's, and Norma brass and just shot the attached groups.

I like how the 17 off looks, but feel that the gun is capable of better than that.

The 20 off is like a perfect vertical line

And the 23 off is a horizontal line with 2 in the same hole.

Do you guys think both of these could be caused by my error or do you think my load might need tweaked?

What would you do from here?

I would suggest trying more seating depth lengths.

Should I try 26 to see if that flyer comes in?

Yes. I would try 26, 29, 32 to see if that helped. If not I would try 35, 38, 41.
