I once saw a load in a gun magazine which was beyond belief. It was (crazy) grains of Unique with a 90 grain jhp. I loaded up 15 rounds and tried them in my Hi-Power. It threw the empties about 30 feet. The primers fell out of the pocket etc.
It was probably about proof or maybe even hotter. I still can’t believe they published it.
I forgot to mention it was for 9mm Luger.
Ahh, the old days of G&A and Ross Seyfried boomer loads!
I used to go to websites and ask loading questions, then realized there are handloaders out there who think a safe load is any load that doesn’t blow the chamber apart.
