You merely lack attention to details. Sizing, of any sort, is just that. It's moving brass to the point of yield(beyond springback). A shooter using a FL die may or may not actually size portions of a case. I use body dies to bump shoulders, and bushings to partially size necks.
With this, there is an interference fit near the web but no sizing(stays within springback). Nor do I FL size necks(as actual FL dies do). I do not FL size -EVER.
Might want to look at a few details yourself and I understand why you are confused by my comments.
Lets make it clear then.
Redington clearly states that their Redington Body die you have been using y FL sizes the body and NOT just bumping the shoulders. The Reddington body die has the exact same sizing dimensions as their FL die and will size the body of any brass that was shot at anything above "powder puff" levels. Forster just came out with their Shoulder Bump die this year and you have been saying you have been using body dies for over two years, so the details mean that you have been using the Redington body die and FL sizing the body in spite of what you believe.
Now I might believe you only feel what you call "interference" the first time you use the case is shot, but I guarantee by the 3rd time, you are into real FL sizing. Cases DO NOT expand to a certain point and stay there forever as you infer. That is just not in the realm of believable.
Also, using a FL die to only partially size the necks will also always FL size the body above the webb too. Measure a few cases with an accurate blade mike and it will easily confirm.
So anyone who thinks they are not sizing the body by leaving the neck partially resized is only fooling themselves. That is a common misconception for uninformed though.
Close to WHO'S MAX? I never implied that this has anything to do with safe limits, or what shooters commonly take as a limit.
The ~57Kpsi max is MY MAX, and I am confident that you would find this as yours as well -if mindful of matching case capacities(and I don't get the impression you are).
This pressure is also completely sufficent for larger cartridges(including those popular in 1Kyd benchrest), given all the case choices & powders available today.
Don't take the context of this out of subject.
IF the experiment is to determine which is more accurate sorting, then one of two things must take place.
1. The "selected brass" is only fired once as compared to other brass selected with different sorting methods, (for example all within 1 grain) Otherwise you are in reality testing a reloading method. That means that there has to be at multiple sets of virgin brass shot, otherwise you are not testing sorting.
2. IF you are going to shoot the brass repeatedly, as Monte seems to indicate, then the test becomes a reloading methodoligy test and not a sorting test. If that is the case then, your 57K (which by the way is not the norm in the BR arena for 90% of the loads) comes into play as you think that works with brass sorted that way. So test it that way. However, Monte has already said that he is going to be going way over that for the normal Palma loads. Pretty sure he is going to be way beyond the "intererence" felt level too.
Pretty sure everyone knows that changing primers changes the load..
Who said anything about changing primers with capacity tests?
I mentioned that due to the fact, the indications are the test will involve repeated reloading using your NS only parameters. IF Monte or you do not use the QL tested primer (that is how you are estimating pressue), then who knows what the pressure really is. We know (by actually pressure testing) that we have of up to a 5k PSI variance in LR primers. Which primer did QL use? That means that if you are using a hotter primer than QL tested, you could be running 62,000 or if milder you could be running 52,000. QL is a good program for getting a starting spot but anyone that believes QL provides accurate pressures is deluding themselves.
QL has you go in and change the default parameters to try and match what you actually come up with. They only tested "standard chambers, standard throats, standard twists" with one lot of powder, primers, cases etc to come up with their data. Their posted warning requires you to compare their data with data in standard reloading manuals and caution against lot to lot variations of bullets, primers and powder (page 4 of their manual).
Reasons that occur to me relate to the same reasons we cull any brass during preps; to reduce wasted time and barrel life. But there is also specific testing going on here, with certain parameters eliminated to isolate other affects.
Pretty sure that "isolating other effects" is not the case if Monte is NS'ing only along with shooting the sorted cases. Two distinctly different parameters, each with the their own effects. So what will the groupings show? Sorting or reloading methodoligy?
Monte was talking of using Wilson NS dies which are real NS dies and is he using the body die? What are we measuring? Effects of sorting or reloading by NS (which we now know according to your using of the redington body die is FL szing the body and mabye partial neck, who knows at this point?)
What are the test procedures to either limit testing only sorted brass shot one time or is the test sorted brass and NS'd against what? A scientific test can only test one item at a time, not two.
Not understanding how any of this relates to capacity testing or results of cases matched by capacity..
That is the key, what are we testing? Virgin cases shot by various sorting methods or testing reloading techniques? CANNOT be both with same set of brass.
Maybe, maybe NOT..
I use neck tension for tuning and know that it's useful and that variance here is detrimental.
I've learned via painful process of elimination testing that primer STRIKE can be hugely significant to grouping. But I've yet to see any basis, or even discussion, for primer weight meaning anything.
And personally, I've yet to see any single parameter affect accuracy more than seating depths.
Seating depth is found once and pretty much stays the same as long as you monitor throat changes and adjust accordingly. HOWEVER, neck tension changes each time a piece of brass is shot and work hardens. Again, a proven fact. Careful monitoring has shown they also do not work harden the same, ergo the need for annealing or some type of sorting again, IF extreme accuracy is the goal. This is the real monstor to control.
Again, of course you need to make sure the firing pin spring is not rubbing inside the bolt causing a drag etc and you have the correct protusion. That is Rifle Setup 101 for BR and extreme accuracy guns.
The discussion of the weighing primers was to show the details that some BR/LR shooters are going to in their quest for ultimate accuracy. Most of us have tried various methods and shot many test groups to determine what works, what is pure BS and what just cannot be proven one way or the other.
I have done sorting and testing by water, the 1% (with other measurements) and using a Juenke and I know what my testing at 1k showed. That is why I would like to see what Monte finds, if he is in reality testing sorting only.
