I haven't done any checking with a magnifying glass.
To my naked eye, the factory loads and the handloads all appear the same in terms of scuffing on the case head. The primers appear the same too.
I know some of you mentioned possible over pressure; I did load these hot. It's a process I've been slowly working up too over several weeks. Accuracy is excellent and I have yet to see any over-pressure signs on any of the brass.
Also, I have shot some of these hot loads in my suppressed AR and the case heads are not getting scuffed up in that one.
The brass from my suppressed AR is filthy dirty so that's how I can tell which ones were fired from which gun.
This is a new gun. I have fired around 100 rounds through it tops.
