Agreed, that is by far the easiest thing to try first. I can also try and resize a touch more, I was aiming for 0.002" headspace clearance.
That's fair, I guess I wanted to establish the limits early, but I see how it could be misleading. It could be that I'm already speeding up and getting more pressure. I'll back it off and shoot more over the chrono until I see MV stabilize, then repeat the pressure test. Hopefully this solves the clicker problem as well.I don’t typically fully trust a ladder to establish pressure at all unless my barrel is broken in. Like a said above not uncommon to see 100 +\- fps.
I actually just broke in a 6 creed. Started at 2850 and ended at 2990.
Velocity = pressure. Even it everything is handling it.That's fair, I guess I wanted to establish the limits early, but I see how it could be misleading.

How many shots did it take for your barrel to break in?I don’t typically fully trust a ladder to establish pressure at all unless my barrel is broken in. Like a said above not uncommon to see 100 +\- fps.

It's a Bartlein, not sure what bore they run exactly. I think my main mistake was focusing only on primer condition and ejector marks to assess pressure. Well that and referencing forum numbers. But again, I've gone further over book max without issue on many other guns, so I don't think "over a grain over book max" is really inherently the problem here.
Depends, last two 100-150 really sped up.How many shots did it take for your barrel to break in?
I have a box or two of new 6cm ADG brass if you're interested, I'd make you a good deal.It's a Bartlein, not sure what bore they run exactly.

"Fixing the chamber" is the bottom of the list of options, and precisely why I posted here to get insight, because it didn't seem reasonable. I've never had clicker issues, and when I started searching, I found Alex Wheelers thread talking about "fixing chambers", so that's why I included it as an option. But I agree, the once fired brass in a different chamber and hot load could be the culprits. Easy to check, I'll report back once I do.
Bryan Litz tested this in his latest book, he shows the speed up can continue up to 200 shots, give or take.How many shots did it take for your barrel to break in?
Haven't tried that yet, I may go this route since it's almost the same price as buying new brass!Does shooting factory ammunition cause any issues?
LRP or SRP?I have a box or two of new 6cm ADG brass if you're interested, I'd make you a good deal.
LrpLRP or SRP?
Thanks for the info. New to reloading in general and trying to work out my first load, on a new rifle of course lolBryan Litz tested this in his latest book, he shows the speed up can continue up to 200 shots, give or take.
That measurement can only be accurately take with a ball mic, at exactly .2" above the case head, so it's a little harder to diagnose based on dimensions and specs.Measuring the fired brass, I see base diameters from 0.470" to 0.471". There is no correlation between base diameter and clickers. However, when I was measuring the bases, I noticed that some cases showed wear marks from the resizing die going much lower on the case than others. So it could be that the height of the max diameter is significantly different case to case just depending on what chamber it was initially fired in, rather than the overall max diameter itself. I was not able to directly correlate this to the clickers I experienced in test either.
I'll bet it does.150 pieces of new ADG 6CM are on the way thanks to @762 ULTRAMAGA, so I'll test with those at 40.0gr to start and see if that cures the issue.

Should have said micrometer because yeah blade mic would probably work better. Yes they do, but like I said they're not perfectly accurate and can make it harder to diagnose an issue based on dimensions and specs. Most comparisons I've seen calipers can be .001/2" off of what an actual mic will read, depending on quality and accuracy of tools too, it could be more.Do you mean blade mic? Calipers seem to be repeatable enough to at least tell some of the story.
