I would work the 23.7 load.
The group before and after have a very close POI and that is a good group
I would throw a 23.5 23.7 23.9 at the same target and see how they print.
Nice shooting

I've never been a fan of VLD bullets, and I think you'll finder better groups with a more traditional bullet from Berger (80.5 fullbore/82 berger) or Hornady (80 amax). The benefit is that it's easier, in my experience, to keep bullets in tune...and they have similar, if not better BC in 223.
That said, I'd go back to 23.7 and play with seating depth...but I'd bet you can get more powder and velocity in there.

I used Wolf primers and at 24 gr they were starting to crater. I'm going to switch to BR4s and starting at 23.4 gr work up again. I agree with you about more powder/velocity but not with wolfs. Of course if I don't find another accuracy node going faster is useless.
I've always had great performance from VLDs as long as I'm shooting over 200 yds. They take a while to "go to sleep". Once I find the node I'll do all the fine tuning at 300 + yards.
23.7 grain area does look good... it's helpful with the .223 to use .2 grain increments, since you're working on charges in the 20 grain weight area.
Probably test 23.6, 23.7, and 23.8 and see how they all look... then you should have a clear winner from those three. Two Boxer may well be right, at the 23.8 grain charge. If this were my target and I didn't want to do any more load development... I might be inclined to go with 23.8 and load 'em up and call it good.

That was kinda my thought.
I'd run an seating depth test @ 23.8gr to find best accuracy, then go choot'em.
No I didn't. I use a magnetospeed and it changes the poi. Now that I've had my thoughts verified I'll do what was suggested and put together some rnds from 23.6 to 23.9 using both wolf and br4s and check speed and ES/SD. QL says I'll see somewhere in the 2950 range. Plenty fast.
Working on y'alls suggestion I shot a few groups today. The target is self explanatory and I added my chrono results for the "winning" groups. If you ever wondered what difference the choice of primer makes, here's your answer.
23.4 grns be load I'd work on to be honest. I'd try using a tighter neck tension if you're using a neck sizing die with bushings and work on the seating depth in .010 increments most VLD bullets like to be jammed to a slight touch also.
At 1.900" the bullet is just touching the lands. I did the seating depth test recommended by Berger but I expanded it to start at .030 jammed all the way out to .080 jump and my rifle seems to like it just touching. I was also able to shoot one group at 300 yds before I ran out of time. 23.8 gr seated at 1.900" BTO and OnTArget measured it at 1.232" Max. I'm new to OCW why would you work the 23.4?
Both targets are printable. I'm guessing your talking about the second one. I'll see if I can find the link and send it to you
It showed a nice triangular group one that can be worked down by few sceneries one primers another neck tension and others be slight powder difference and as already mentioned seating depth.
if a group shows vertical or horizontal stringing there's no way to eliminate it although it may dissapear some at short range it will show back up at longer ranges. The triangular groups is what I seek in load development and I do manage to get them down to a very small group by small tweaks.
