Metonymy

So I have two different bulk boxes of Federal .22 ammunition.

One is the standard maroon box, 550 round value pack. The back of the box shows the following:

Bullet weight: 36 grains
Style: Copper plated hollow point
Velocity: 1260fps at muzzle, 1000 fps at 100 yds
Energy: 125 ft lbs at muzzle, 80 ft lbs at 100 yds
Drop: -5.6" at 100 yards (assuming the gun is sighted in at 50 yards)
Load: Load No. 750

The other is the blue "Champion" 525 round value pack. The back of the box shows the following:

Bullet weight: 36 grains
Style: Copper plated hollow point
Velocity: 1280fps at muzzle, 1020 fps at 100 yds
Energy: 131 ft lbs at muzzle, 83 ft lbs at 100 yds
Drop: 3.4" at 100 yards (assuming the gun is sighted in at 50 yards)
Load: Load No. 745


It's easy to see the difference in characteristics of the two from this information. The "champion" round seems to be a little hotter and has a much different trajectory @ 100 yards than the standard round. (It seemingly climbs instead of dropping?)

Here's my two questions:

1) The information on the blue "champion" box does not match what Federal has listed on their website for this load. The data on their site for the 745 load (the blue box "champion" round) is nearly identical to the data listed on the back of the maroon box 750 load.
Federal Premium - Rimfire Details
What gives?

2) The detailed ballistics data for the 750 load (maroon bulk box) is not listed on Federal's website as it's not part of their "premium" ammo line. Does anyone know where I can find the details?
