20"barrel, choked

[Backslash]

If you have a 20" barrel, choked , how tight patterns would yo have at different ranges and whit different chokes ?

This is the only way you will ever know.

The patterning board is your friend.

Every time you change a load, the pattern will change; every time you change the distance, the pattern will change - as mentioned, go to the pattern board and see not only how tight/loose the pattern is, but where it is in relation to your point of aim - is it where you pointed the gun or lower/higher/right/left??

I don't believe Backslash has his 20" barrel with choke tubes installed yet, so he can't pattern the gun. He has the cylinder bore barrel at that length, but is trying to get a local (Sweden) gunsmith to install them for him. His question is more rhetorical at this point.

Hope this helps.

The length of the barrel will have no effect on the pattern - the choke will.

Here's a chart from Briley you can use as a guide:

While that is a sporting clays chart, you can get an idea of what chokes tend to work best for that application at the distances mentioned.
