I would test this, 42.3, 42.4, 42.5, 42.6, 42.7 just to make sure you arent seeing a fluke.
Put up some 1-2" dots only on blank paper (smaller aiming point)
Reshoot it but shoot them as individual 5 shot groups and take plenty of time. (assuming RR style means 42 then 42.2 then 42.4 etc and back to 42 and back down the line)
42 and 42.4 have the best vertical spread. Hard to say where the horiztonal is coming from, wind, getting off the gun, trigger pull, etc.

That is precisely how I shot those targets and that is a 2 inch dot. I went up the scale one shot with each charge weight. Then a cooling., Then down the scale the same way cooling. And then up the scale. There was a bit of a breeze from the right.
Yeah I would say shoot them as groups.
If you're moving, breaking your position, etc between shots in each group there could be some variation caused by that as well.

I will try that, it will probably be next weekend before I have access to a 300 yard range. The Hogden manual showed a maximum size charge weight of 42.6, but I was showing no high-pressure signs, I had an experienced reloaded observing. In another publication I saw loads with the same powder up to 44 g, that is H4350
I am assuming that you are not familiar with the OCW method of load development. This is exactly not what he is trying to accomplish.
You can and probably should do OCW at 100 yards in order to remove the possible influence of wind on your results.
I'm familiar with it, I use the same process for my ladder tests.
But if I have something that looks like his targets, I would be trying to eliminate a difference in my shooting as much as possible.
Yup. At least 5 rounds of each. I'm doing that next week with 2 powders in my 6.5CR/147ELDm loading.
I’m thinking y’all are saying round robin again with the chargeweights Spife suggested, at 3rounds each weight? At what range? 100-200 I can do easily, 300 yds will take some driving.
I like to do 5 rounds. It’s easier to judge with more data than less.
What is your opinion on range? I’m hoping to get a new can of H4350 today, this one is about gone and don’t want to start over again.
If its really calm and youre confident in your abilities then shoot it at 500.
If you arent confident that you cant blame yourself for fliers then shoot it at 100 to get a bit more confidence that it was you and not environmentals that threw the shot out wide.
I shoot tests at 100 more frequently than I do at distance. But I always make sure it still works at 500 before I call it "done."

None of that matters when we can see the results on his targets.
One area looks much more promising than the others. (not denying more complete info wouldn't be helpful)
But its also mostly in his previous posts.

i dont like any of them and wouldnt even try chasing a load from that...id reshoot the whole thing at 100yds like a couple of ppl have said.
Asking because a 200 range is easy but longer range will be next week and I
Just to bring you somewhat up to speed, nobody but Hogdon has recommended a load that I am loading and I find them very conservative compared to some that I have seen. I asked if anyone had a pet load on a completely different , short barrel thread totally out of curiosity, and what is the harm in sharing findings? Not that there isn't a ton of official data online, but very little in print on 6mm Creedmore. It's a balmy 70 degrees here in South Texas, you should come down and visit, it's amazing what some pleasant weather and friendly people can do for one's attitude.

I think that Mr. Spife is right. You stopped at 42.6 and said that there is no pressure signs. You still have vertical and that suggests that you need more powder. Good groups are small and round. I would keep increasing powder in 0.1 grain increments until
(a) you go through the node and see your groups grow or
(b) you see pressure signs.
Ok, the five matching targets, four rounds 100 yds, 6mm Creed. See anything? I may be looking for miracles here

Yep. 42.5gr and play with seating depth to see if you can find a slightly less vertical group. That will . But honestly, a .3-.5moa group at 300 might not need much tuning depending on your skill and equipment.
If this is a custom barrel, I'd say you could likely tune a bit more. If it's a factory Ruger or someth4 similar, I'd take .5moa or better and walk away smiling.

16.5" Criterion barrel. I'm thinking node may be narrow. Which way on seating depth? Or better question what increments?

Prolly .010” increments. Shoot again, see what looks best, and if you want, mess with the best, +/- .005”.
Well I'm not sure where you are in reference to your lands already but generally I do the following:
First pass 4rounds ea:
- -.010
- -.040
- -.070
- -.100
- -.130 (as long as not seating ogive past neck.)
- -.025 (.015 longer than best node)
- -.033 (.007 longer than best)
- -.040 (best node above)
- -.047 (.007 shorter than best)
- -.055 (.015 shorter than best)
