I got a TruGlo Gobble Stopper ported choke.
And a Hunters Specialties The UnderTaker
Both from Wal-Mart from layaway.
A good way to get hunting supplys when you are not rich LoL

Both .665 12 Ga

I put them in a winchester model 1300 pump

I shot both the ported choke kicked just as much
As the non ported choke.

They both patterened about the same.

The UnderTaker seemed to do just a tad better than
The TruGlo so I kept the UnderTaker in the barrel.

They both patterened guiet well.
Wether you use a ported or non ported is up to the person.

The best thing to do is just get both and see for your self.

What ever you do be carefull and remember to use ear plugs,

Good Luck
