Federal cases have slightly softer brass than some other brands, and is somewhat thicker, so when used with the same loads that were developed for use in thinner / harder brass, pressure is higher and primer pockets tend to loosen early. It gets a bad rap from people who want to shoot the maximum pressure loads that their rifle will tolerate. If you load high pressure loads with Federal brass it only lasts a couple loadings. If you shoot moderate loads, it lasts for many loads. It is as consistent as most, not as good as Lapua or Norma but pretty good.
