Hi, I just used my Dickinson 28 this last weekend on our Sharptail opener. The chokes I used were Lt Mod/IM, but, and here's the rub. The tubes as they are marked are looser than what they state.
My Dickinson's bore's measure out at .546 (L) and .545 (R), On measuring the tubes with those bore diameters the chokes are:
Cyl Tube is Cyl
IC Tube is Skeet
Mod Tube is Lt Mod or very tight IC
IM Tube is Mod
Full Tube is IM
So, without measuring you guns bores/tubes it's hard to say what choke your really shooting out of that tube. Of course patterning is the only way to learn what your tubes are throwing.
As I said, I used my Mod/Full tubes and the gun did the trick, was able to shoot a limit with all the birds stone dead when they hit the ground. The average distance on these birds was about 30yds (they were spooky for some reason).
Good Luck,I hope you find a combo that works for you.
Greg
