You can use just about any 2 3/4" load that you want. Since you are most likely taking the shot at 45 yds and under use #6 shot and really fill in the pattern. Use #5 or 4 only in the second barrel (if you must) if you screw up on the first shot. Turkey hunting is a "head" game and #6 usually patterns much denser. I have patterned 8 or 9 SxSs from 12 gauge to 28 gauge and eveyone of them gives denser patterns with 6s.
