I have had good service from FC brass in several cartridges, and have loaded quite a lot in .222 Rem, .243, .25-06, .308 Win, .30-06, 7x57, 7x64, and .375H&H. I have found very few loose primer pockets, and this only in .308 cases. I don't load or shoot .223, and wonder if that cartridge is the source of most of the bad reputation?
One other thing, I don't just load indiscriminately with the same powder charge in all cases. I sort cases by brand, or at least by weight. Federal brass is often heavier, = lower capacity, so charges must be reduced a wee bit. If you don't do that, and you're already loading a max load for other brass, over max pressure is likely, and corresponding poor case life.
