[Unclenick]

You can look the loads up on the Hodgdon site, as Stick_man said. In general, you'll find Clays is very fast and uses a very light charge weight. Low recoil but low upper velocity for the pressure reached as well. This is because its pressure peaks before the bullet has moved forward much, and thus it has all its gas crammed into a very tight space. That limits how much it can safely make and means the pressure drops fast as the bullet moves forward. That's why the charge weights are small and why the velocity achieved is low.
