I have used several chokes from several manufactures on my Beretta and Benelli with 1 1/8 #1 steel shot reloads @ 1620fps.
Trulock chokes have patterned better as Carlson and as PM. Terror chokes performed even better but I had to junk these POS as they swelled and got stuck in my gun (2 of them).
Trulock and Carlson chokes have shown better patterning with less restriction on the choke. IC and M performed better as IM chokes. I do 90% of my hunting using IC/M chokes and the rest with PM code black duck for geese long shots.
Another thing to keep in mind is the choke you are asking is not warranted for steel shot bigger than#2.
Good luck
