Kicks Chokes and Federal Grand Slam

[Longshanks]

Anyone had any luck shooting the Federal Grand Slam lead loads out of Kicks chokes. Have Rem870's with 21" and 26" barrels. Kicks .655 and .665. Have seen great patterns with Fed TSS and Kicks chokes. Just curious if anyone found any success before I go out shooting these guns getting the dog .... Kicked out of me.
