Have been asking the same question. Have the Hastings Non ported .655 and .665. I'm not a choke builder but Hastings chokes are made of 17-4 Ph stainless steel and they are built like a tank. I can't see why they wouldn't work. I have been waiting to see if anyone has any experience with this but no luck so far. Kicks did tell me that it would be fine to shoot through their .655 choke.
