does porting affect hunting velocity??

until this past spring i felt the same way. but then something funny happened. i bought a chomp-n-choke tube (ported) for my o/u for spring turkey hunting. i went to pattern it and had the other barrel with a std. x-full that i had in it.
i shot a load at the patterening boards out of the c-n-c- (.670)barrel, then shot the other load out of the x-full (.685)
WOW a marked dif. in felt recoil, i had my buddy try the same thing with my gun not telling him what i was thinking. his comment back to me after firing the second shot was "did the second barrel have a hotter load in it than the first?"
so all i can say when shooting some heavy turkey loads out of my gun there was a felt difference.
