Absolute fact!I would only add, learn to read the conditions. It’s too easy to get lost in the minutiae of loading only to get schooled by the shooter who can read and shoot in the conditions on the range.

His response was a way of saying learning to read the conditions has more effect than working about .002 headspace variance.Reading the conditions does you no good when you can't hit the target because of consistently being plagued with unexplained fliers. As was the case with the rifle I was shooting last season.
Now what does your response have to do with the question asked about measuring headspace?

I started this adventure 2.5 years ago with a Savage Axis in 223. I then moved to a used Savage Model 10 223 and learned much and acquired some valuable trigger time.. Enough to know I needed a better rifle. Another season on the league and I will be ready to move on again to a good aftermarket barrel. Can now shoot pretty consistent 3/4 MOA at 100, Sub MOA at 200 and just over MOA at 300 yards. I am happy with my progression.
I don't think headspace is your goblin. It sounds like a situation where you may be playing in the .005 jump to .005 jam area where some are touching and some are not. I'm not saying that's the problem, but the indications sound that way. You might be riding the fence on a seating depth node which may present the same.... if you have a group of 15 rounds run one group +.005 longer keep one the same and run one group -.005.Wow I guess we can stretch the topic any which way.
My question has been answered so if you all want to continue with this line feel free.
I would try to focus on finding the explanation for the consistent…inconsistency’s.
1.460" +/- .001" Measured head to datum. If a crush fit is felt while closing the bolt, bump. 001" more.what is a suitable parameter for shoulder length measurements?

When the shell holder makes contact with the bottom of the fl die, head to datum is better controlled.
Redding Competition shell holders help with this.Redding Competition Shellholders are packaged in five piece sets in .002” increments (+.002”, +.004”. +.006”, +.008” and +.010”). Each shellholder makes head to datum LONGER.
While at the bench sizing these the other night I asked myself just this. Is it time to move up to a better shellholder and maybe even a better sizing die.
You stated an indication that you may not have caught or realized. If you had to adjust your die, the brass has different hardness. Those would definitely get removed from my group.What I am using now is Lee and moving the shellholder back and forth between presses.

Switching presses for the same operation is inducing a change that is not required. If your sizing on one and seating on another then swapping shell holders doesn't matter. Keeping a shell holder per die will be the ticket.What I am using now is Lee and moving the shellholder back and forth between presses.
The shell holder you size with is important to keep with the sizing die if your locked down.I dont feel thats an issue. The die will do the job. The shellholder will do the job. I have Lee, Hornady, and Redding dies and Hornady and Lee shell holders. The dies? Yep, they all work. The only difference Ive seen with the Lee vs Hornady shell holders is that the Lees are just a hair looser.
I know some people double strike on sizing. Size once, turn case 90 or 180 degree, size again. But as long as the die and shell holder is machined right, its probably an old wives tail.

Sorry for the tangent.
To make this much more simple maybe the question should have bee asked as "what is a suitable parameter for shoulder length measurements?" Targeted length or +/- what?
You said you switched presses, I covered both basis in my response, sentence one or two.Who said anything about switching presses for the Same Operation?
How wide are your flyers? It’s quite possible - even quite likely - that flyers outside of the group can be environmental.
Are these flyers happening with the musical chairs bullets? Or with all? How’s your trigger weight vs. your rifle weight?
Flyers are USUALLY shooter POA, trigger control, wind, and neck tension - in that order (once you’ve cleared the bar of using quality bullets).
Don’t be too hard on that rifle either. I have a factory Savage 12 in 223 which will print 5 rounds into the .1’s-.3’s even with cheap crap factory ammo.
