I want to port my 590a1 barrel.

I have to agree with Lee, there are lots of modern buckshot loads that will perform well in most any shotgun. However, having had the privilege of shooting a Vang shotgun, the reverse becomes true. The Vang will pattern just about any buckshot load well.

Question is how much buckshot do you plan to shoot? If you are going to shoot lots of it, you may save the difference between premium shot shells and the cost of the Vang barrel. If not, just buy the premium buckshot.

The porting is just a portion of what Hans Vang does to these barrels. I know he lengthens the forcing cone, and I have heard that there is some type of jug choking. I don't truly know exactly what all is done, but I do know that the results are impressive.

from my relatively limited experience, porting has almost no effect on muzzle rise. i only shot a few rounds with a ported bbl for my mossberg 930 before i switched, the gas that came snarling out of the porting just annoyed my fellow shooters, as well as myself.

Snarlingiron,

As I understand it, what Uncle Hans & crew do, is basically to back-bore a given barrel, leaving a short segment at the muzzle at the original bore diameter to serve as a choke. Exactly what the internal geometry of a Vang barrel is, I can't say for sure, as I've never seen one sectioned or seen anyone take a Stan Baker bore gauge to one. But that's my understanding of what happens.

FWIW,

Don't count on it. Damage to the Cochlea and hair cells(neurons for hearing ) is permanent. You may get a hearing aid but you still will not hear the picolo or high frequency sounds well. Still don't believe me? Call and ask your nearest ear doctor or Otologist.

Id rather spend the money to have the gun modded to take chokes.

I have a shotgun that with an IC choke and it keeps all pellets COM on an IDPA practice target at 20+ yards from regular Remington 00 2 3/4 express loads
