I was wondering about that as well. I think a bad port would only affect accuracy since it changes the harmonics of the projectile, however it should not affect velocity that much. No doubt one of the bookworms around here should have an ariticle link on the subject. (wink wink, nod, nod, nudge, nudge)

Just remember that all the reloading manuals that state velocitis for their recipes are just an average from the test they did. And they also state that you may not get the same results from your particular gun. Same thing for the numbers on the box, they don't know what type of gun the ammo is going into they only know that its going to be for that caliber. Lots of things will affect velocity, barrel length is one. Chamber specs, temperature, altitude, what God may think of you, will the Twins win the World Series, and how the bullet was loaded will all play a factor in the velocity you get. You have to just experiment and get a consitent load, take out all the variables and constantly test to get the velocity and accuracy you want.
