I have chrono'd the Rem-UMC and Federal Champion out of 4 guns, a 5906 (4") a 3913 (3.5") a Sig 290 (3") and a Kahr CM9 (3") ...and done a side by side out of 2 of them
They essentially are the same with the UMC being slightly faster (10 to 20 fps) (F=1013 v R=1030 in the Sig and in the 5906 F= 1092 & R=1101)
Blazer Brass and Wolf were actually slightly hotter.
