SumToy for T/C

[ccaldwell]

I was just wondering if anybody has used a SumToy choke on a T/C Encore 20. I'm planning on using Federal Heavyweights and I'm looking for a good choke.

I have a sum toy 562–5 but I've never been able to shoot the federal heavies very well it shoots nitro sevens or heavy 13 sevens extremely well at or just over 200 in the 10 every time with the nitro 7s @40 yds
