In case of the overwhelming (sic) evidence .I also rest my case. On another forum I have seen Physics reinvented. And now I can't take it anymore to see Statistics reinvented. (Steak example included.)
For me this is clear case of the 2 articles :

!) I am always right!
2) In case I am wrong,Article 1 applies.

I sympathize with you Renaudw. Some people have problems to understand
the basic principles of designing experiments and test procedures.

Dogchaser you can find a lot of books on statistics ,also on ballistics.
Read them and try to understand.
In case you want to use more invective go ahead.

I repeat what a fellow researcher used to say when someone was displeased with the outcome of experiments, because they did not understand.
I have been shouted at by more important people.

I love the smell of contempt in the morning. Or is that beer?

The two making the problem here, don't have any experience, developing loads, actually testing them or applying SAAMI standards.

The ONLY thing either of them has done is comment, incorrectly, on a data sheet that Mr Armbrust produced.

I suppose that Mr Armbrust doesn't understand what he is doing either?

Let us please end this posting

The OP got this answer.

16GA would you please cap this thread?

Thanks to all for the entertainment.

It's been a long cold winter. Spring's coming. We'll all soon find better things to do. Very Happy

cj dawe,

You must understand the two conflicting reloading premises first. In metallic reloading you 'work up' from the starting load watching for pressure signs as you get toward the max load. In shotshell reloading you always use a published and tested load as it is written.

I know that can be a predicament when you live in a remote area of the planet and cannot simply go to a local gun shop to make component purchases. I heard the same lament from professional hunters in Africa who preferred to load their own ammo.

data varies so much shot to shot that it really is only a guide. If you think that all the shells loaded to a single combination are going to give you the pressure and vel thats written there over and over again then you should read about load testing and find out how little is really learned from it. the stats are in a very large ballpark to say the least.

I can't resist........exactly how large is the ballpark?

How much does data vary shot to shot?

Test station to test station? How much can pressure vary? Why can it vary that much? How much can velocity vary, test station to test station? Why can velocity vary that much?

There are definite answers to all of this. Where do you find the answers?

This type of thread ALWAYS boils down to, everyone wants to hear what they want to hear so it fits into their little reloading kingdom, whether driven by price, ego or stupidity or all 3. Just like anything else, that is manufactured (and you are manufacturing ammo when you reload) there are tolerances.

And just because you aren't wearing your barrel for a neck tie IS NOT definitive proof that you are reloading properly. Thank the firearm engineers for over engineering the firearms so that doesn't happen.

Swapping primers isn't dangerous, it changes the ballistics so that you aren't getting what you should.......apparently that doesn't matter to most.......swap away.
