Sumtoy Chokes?

[SumToy]

Sumtoy, what choke would you recommend for a Rem 870sm and the longbeards? I want a fairly open pattern at 20 yards though, I would be willing to give up the bigger numbers at 40.

We have not been able to get them to open a lot at the 20 mark.  I would run a cheap shell for that.

sumtoy, what would you recommend with 535 with nitros I want it tight and a long range choke

or what you recommend to get the best pattern out of the 535

It has a lot to do with what shell you get.  It 7's I would run something in the 675 to 685 rang.  The mix load 4,5,6,7's I would leave with them and go with the HV13.
