We had a thread that had chrono results of magnum vs. special ammo from short barrels. That showed that while you do get a good increase in velocity from magnum, it still dumps serious speed from the short barrel.

But do we have a thread with chrono results that show real value in standard vs. +P or even +P+?

From the serious drop in velocity that magnums suffer, I'm curious if +P is even really worth use in a snub with the short barrel to burn the minor amount of extra powder. In a three inch tube I would think it would show, but in a 1 3/4" tube??? How big of a difference can we be talking about here???
