Looking at the Lyman 49th edition the max velocity of a 200 grain bullet in 10mm is 1148 and 41 mag is 1392. The low end on the 41 mag 200 grain velocity is 1157 so you would be correct I that it is very close to 41 mag power. Just not max 41 mag power.
I really like the 10mm. And it's a lot easier to conceal in a 1911 than a 41 magnum in a desert eagle. I like the 180 grain speer gold dot hp loaded over 12.7 grains of 2400 at a velocity of 1214. I tried haed to use 11 grains of blue dot for a listed velocity of 1295 I just could never get it to feed in my RIA. It did fine in the Sig 10mm
