I don't know anything about the DND Haymaker choke's shooting characteristics, but if it is, as you indicated, an IC clone it probably won't give you a turkey killing pattern w/ the Federal HW shells. The Haymaker is advertised as shooting all wad types and doesn't have the IC's wad retention rings. I've shot a lot of the Federal HW's through a bunch of chokes, and even with allowances for the reduced number of shot in the HW shells, did not find a choke which produced patterns as good as an IC w/ EM Hevi13's. With that said, one of the great things about this site is the number of knowledgeable shooters who can direct you, via experience and trial and error, to a choke combination which might work for you in a particular gun. It's an extremely expensive and time consuming proposition to evaluate gun, load, tube combinations, especially w/ the Federal HW's. You need to ask, " What choke is working in a Stoeger M2000 with the Federal HW shells?" You can buy a choke for about the cost of two boxes of the Federal HW shells.
