You don't have to believe anything from me or anyone else. It's not about believing what someone else says. It's about realizing the manuals aren't gospel and that their data can vary considerably from one to another......and understanding why that is. Guns don't read. My load or your load or anyone else's can be very different from some manual and it'll be perfectly fine in a particular gun. Read the second paragraph in my post again. And no, I said brass is the weakest link and it will tell you what's happening.
