>7.5gr's of this powder will put it on the edge of the pressure map?

Hodgdon shows 7.1 grains as max @ 1150 fps and 35,600 psi so 7.5 would be very close to the 37,500 psi possibly.

I have shot 7.4 and it performed much better. I wonder why Freedom doesn't switch to Power Pistol and get closer to the rating?

Cost?

I wonder why so many manufactures overrate their ammo?  Don't they realize that forums like this, or anyone with a chrono can see thru that?

I've received 500 rounds of this stuff, and gone thru a box of it already.  It's fine for the range, and probably the cheapest 10mm ammo out there.  I can't afford to shoot Underwood all the time at the range.
