I didn't try hevishot through it. But several lead loads didn't give me acceptable patterns with the factory turkey choke. It's diameter is .674. You'd be well served to look at an aftermarket tube somewhere in the .655 diameter. I've had very good results with the .655 comp-n-choke.

BTW. I bought mine this spring in the HD Advange for $399. You'll see them in stores from $399-450.
