I can vouch for PRVI being slow. The 140s I graphed were 2225-2250 fps.

In defense of the Swede --- my comment related to the only factory ammo I 'remember' graphing. I had some WW 140s but I don't remember checking the speed.
OTOH ! ! I handload 120gr NBT w/ 4350 (either H or IMR) at 3000 fps. I didn't mention because the OP is asking about Factory ammo.
120gr @ 3000 AINT bad for the case size. Consider the 6mm Rem 100 gr @ 3100.
