Shotgun choke tube restrictions

Does anyone know the amount of restriction various choke tubes offer? I am looking for information on Remington 12ga choke tubes. The list on Remington's website isn't available anymore.

Did you look on briley's site?

scroll down to Pattern and choke

I did not look at briley. I assumed all brands would be a little different.

BOBO that is great information, but the one I am looking for is a Remington choke called "singles".

best I could do

I guess that explains a lot. I was hunting quail over my dog and I couldn't hit anything with this choke. I bought two new chokes. One was supposed to be between skeet and Imp Cylinder. The other was supposed to be between modified and full. I guess I picked up the wrong one. I shot this for 1 1/2 days before I decided to pattern it on a dirt hill. I was amazed at how tight the pattern was.

Straight from Remington
Choke constrictions are:

Full .691
Singles .700
MOD .709
IMP .718
Skeet .723

That is total so to get the actual restriction you need to subtract the choke diameter from the barrel diameter.

Typically it goes like this:



So based upon these numbers your barrel is around .727-.728

I didn't answer originally because I had never heard of a Singles choke.
