I'm replying to your post in the "Primer Recommendation" thread.
I've only used SSA brass for reloading; so I can't compare it to any other brands. Some of my once fired brass had loose primer pockets, but I think that's more due to me using Winchester LR primers, which are a tad smaller than some other brands. I will start using CCI primers on the twice fired brass, and am hoping the loose primers decrease or disappear altogether.
All in all, taking into account my extraordinarily limited knowledge and experience with reloading, I've been pleased with the results from using H4350 and 140 Hybrids with the SSA brass.
