Ported or Unported Chokes???

[WaterfowlShooter19]

I just purchased a Browning Silver Hunter and i am goin to put a long range patternmaster choke on it but i dont know what the difference is between a ported or unported choke. The performance will be the same i asume but is one better then the other. What is the difference??

Thanks everyone

Porting in the chokes is similar to porting in barrels. In theory it reduces muzzle climb and felt recoil. It will be louder.

Porting probably won't make much difference in felt recoil with a shotgun. It generally works best in firearms where the weight of the powder charge is a large percentage of the weight of the bullet, such as with magnum rifles.

I have a ported barrel. It really dosn't reduce recoil or muzzle climb. Just makes your shotgun louder and harder to clean.

Tjhaile very interesting theory ????

I have both ported and non-ported chokes and have never noticed a difference in noise, recoil, or muzzle rise when switching back and forth. I do however, wear ear protection.

This thread just answered my question.

Tjhaile very interesting theory ????

John Ross, author of Unintended Consequences has a more detailed explanation here:

http://john-ross.net/recoil.php

Recoil results from the momentum from two masses being accelerated to some given velocity: that of the bullet and that of the powder. The greater the fraction of the total ejecta that is comprised of powder, the greater the potential gains from a muzzle brake.

The only diifference I have found in ported/unported chokes, is the ported chokes are a real pain in the ass to clean.

What would you guys recommend if it doesn't make a noticeable difference. The ported ones do look pretty good tho

I put a ported turkey choke on my 12g 870 last year and I noticed it had less recoil.

Another thing to remember is if you are intending to use any Federal shotgun ammo with the flight-control wad, Federal recommends against using a ported choke. Apparently the flight-control wad is designed to stay with the shot column, & the ported choke stops the wad from doing this.
