And steve,I have toagree with you, both the 7mm and the 280 show alot more velocitiesover 3000 fps. than they do under the 3000 fps mark.
Now that I look at it, I don't know why there is so much of a difference between the 2 charts. The chart that doesn't show barrel lengths hardly even has any velocities less than 3000 fps. (this is strange)
