Ok I'm going to post this question for discussion to see different opions and what is average answers. If this was your target and you wanted to shrink your group at 1000. Would you start with seating depth or powder charge?
Competition tuning

That could be you just haven't hit a node with the powder charge. I'd also try a different powder. If you have to use that powder then try seating depth in increments of .005" out to .040". Implement flags and make notes of wind condition and chronograph every load.
What was predominate wind condition? Six, 5 o'clock?
Honestly I can't say for sure, I go off my last sighter and let them fly as fast as I can.
Bench , neo front, flat top rear
Shouldered, these were match test loads no chrono
Btw it was shot at cool acres this past weekend . Very challenging range but great to shoot there! My first time but will be back.
Inconsistent pressure and vertical position in the shoulder causes vertical stringing.
Thank you
The group is only around 3 inches wide and 8.5 inches tall, so I believe it is mostly load. Inconsistent shoulder pressure can cause some of it also. I prefer to tune at distance i will be competing at. I feel when you get it right, it tends to shoot through conditions. A ladder will help find your node. It is also very important to have the parallax out of the scope.
It would maybe help to know the cartridge, bullet, primer, powder and load. Matt

I agree with Matt 100%....without knowing all the particulars and based solely off the group pictured..I'd say the powder charge isn't quite right.

It would also be good to see the shot order. A condition can blow your group vertical like that as well. If they alternated high and low, then its less likely a condition. But if they went in an order like below, the condition would likely have gotten you. Or the opposite but still similar order you would have caught the end of a condition between sight in and the ol famous "commence fire" (for record string)
Yes both
I would start with a powder ladder
