Federals are the most consistent and accurate primers you can buy. They are a little softer and easier to set off, that is why they are recommended for match guns with light loads. I've probably loaded over 200,000 Fed. primers and have never had a problem. I use Fed primers in everything because they are the most consistent, and that includes high pressure 22-250 loads around 3900 fps.
