Gentlemen,

At the risk of causing descent I must say that 400gr at 2400fps is simply to much of a good thing.

I believe the 450/400 proved beyond reasonable doubt that the optimal velocity for a 400gr 40 caliber solid is 2150fps.

As a coincidence, the underloved 400 Whelen delivers that in a standard action with 5 down and 1 up capacity.

Food for thought and American made, even the Donald could not argue.
