Rost, I've loaded lots of once fired brass as well. That includes some semi auto rifles like those made by Remington, Browning and a Colt AR-15. I've never seen the shoulder of a case blown out that much.
That and the fact that the facory ammo is loaded pretty light. And then the Accurate Arms/Ramshot data for this round is very clear that this round goes critical very easily. Ever see any data that advises one to increase one's loads by .1 of grain at a time ? I've seen data that said to sure and use exactly the components exactly as listed, but not anything like increasing powder charges at .1 grain intervals. They also have much different data listed for the longer bullets of the same weight.
I've been reloading ammo since 1958. I've never blown up a gun or even damaged one with reloads. This round, however, makes me very cautious because I've known lots who weren't very cautious. E
