How did it substantiated your statement while it did the opposite with what @ileaveuptiers posted.? He gave sources along with his reasoning on why Delta 6 was intended and why it wasn’t deemed unusable due to barrel wear.
You have not
Just because you have a documents doesn’t mean you understand it. This was quite evident with your misunderstanding of Delta 3.
The burden is up to you to provide a counter point on why your statement is correct.
A screenshot of the document along with your reasoning will do however not doing so makes you look like a liar and people will take any statements from you heavily with a grain of salt.
Rather than denying any of these points (which you will most likely do), provide the counter points to @ileaveuptiers. Or do both, I don’t care
