I bedded the action on my White Thunder shotgun. The gun just came with the Xfull choke that I use on small game mostly squirrels out to 30 yds. I use 75gr of triple seven 2Fg. felt wad/ 1 1/4oz. magnum #6 shot in slotted plastic shot cup and shot card. If I miss it's me an not the gun for sure!
I have the .665 turkey choke, but haven't tried it yet. Turkey's are getting to be scarce here as well. Good luck with your shotgun they are great guns!
