Question about damascus barrels and turkey loads

[Dennis]

I just checked an old, "Winchester Shotshell Game Guide", I have had for many years and it indicates for turkey hunting with a 10 gauge to use 2 1/4 ounces of shot size 4. For a 12 gauge it indicates 1 1/4 ounces of 4, 5 or 6 shot. For a 2nd showing for a 12 gauge using Double X loads it indicates the same shot sizes of 4, 5 or 6 but a load of 1 1/2 or 1 7/8ths ounce. 16 gauge uses 1 1/4 ounce of 4 and 6. 20 gauge uses 1 1/8 or 1 1/4 ounce of 4 and 6 size shot. It really says much of what has been discussed here already. I am assuming my 3 frame 10 gauge should work just fine with RST 1 1/4 ounce load of 4, 5 or 6 size shot. The wheel is dated 1987.
