My guess is I got a fast barrel and the thicker lake city cases are giving me a boost. And I'm not complaining. I've had mine over 3000 fps but the accuracy wasn't there so I backed it down to the sweet spot. 46 grains in my rifle shows signs of pressure with flattened primers and slightly sticky bolt lift.
