I sort out all my RP brass out, for it has a history of being thin and soft. Been doing this for decades, for it's nothing new. It's fine if your going to shoot over size lead bullets. The bullet will make up for the 0.001" lost in the brass. I also don't like the way RP over cut/bevels the primer pockets either. Reduces support which I have had primers blow due to this if I use softer cap primers.
