At the top of this page under "Search site" type in "Sa-08 And turkey hunting?".There is a thread there that will tell you the different after market choke tubes that will fit the Sa-08.Your full choke tube may work fine,you will have to pattern your gun at the distances you plan to shoot with different size shot.Shot size 4,5,6 is mostly used.You probably know that already though.I would suggest though that you get an after market turkey choke tube with a tighter constriction.Good luck,I am looking forward to our season that opens April 2 in Texas where I hunt.Where will you be hunting and what type calls do you use?
