Regarding primers for shotgun, I bought 1000 Nobel Sport to try them and my Browning BT 100 will not fire half of them, they work fine in the Remington 1100's. The firing pin spring must be a little on the weak side, but it will work fine with Winchester or Cheddite. The cup must be harder on the Nobel, the strike is lighter on CCI as well.
The question is, in your experience, do the Federals seem to have a softer primer cup than other brands? If so I am sure that it would carry over to the shotgun primers as well.
Thanks
