I use the SBE with the factory turkey choke. I shoot 3 1/2 " hevi shot #4 and get a great pattern with confidence to fifty yards atleast.
I have heard that the the rhino choke with the hevi shot has great success up to 70+ yards but getting the turkey's in real close is all the fun.
If you get the briley choke let us know how it shoots!!
Good hunting!!
