They were not. I did a 10-shot drop test and then loaded 6 shells on a PW 800+. I wanted to test what was coming from my loader, not "lab test" shells.
I have loaded 10 shells as requested by a manufacturer and I am sending components for another 25 loads. I will report back after I receive more information. As
@Silver_Is_Money moniker states, "You can evade reality, but you are not free to evade the consequences of reality."
Your tests were done based on your procedure because you were looking for a particular answer to a specific situation.
That's what testing is for... answering a question you can't answer yourself.
However, there are a few people who disagree with your testing procedures, and I think I understand why...
I think most people would like to see as many variables removed from a pressure test as possible, although that may not be what you were trying to accomplish.
For example, you did a 10-shot drop test to determine the average shot drop of your loader. Then you loaded 6 shells for testing.
The variable in this case is the assumption that the next 6 shells would average about the same as your previous 10.
Although I don't doubt they probably did, that's not an assumption that can be verified, which makes your shot drop value a variable, not a constant.
The same can be said about your powder drops when not individually measured. Probably correct, but not individually verified before testing.
Also, how a shell is loaded can influence a pressure reading. Sending your components to be loaded on a different loader introduces additional variables.
I'm pretty sure the values you received were quite accurate and exactly what you were looking for when paying to have them tested.
I think the big difference is the fact that your answers were not for the same questions as other who send shells for testing.
Your answers were for your questions only and simply can't be used to answer the pressure/velocity questions of others. Good luck!
