choke constriction

[Dean Romig]

How does it pattern in what diameter circle and at what distances??? That should be a better indicator of effective choke.

[Bill Murphy]

Your chokes are very full. Parker 28 gauge full is .020. In a .410, .023 is over the top.

[C.O.B.]

I haven't patterned it but based on what it will do to a target even using the std AA 2 1/2 skeet load I figgured it was very tight. I think these will see a trip to the gunsmith and get opened up considerably.
