I'm not opposed to screw-ins. I have a number of guns with them and a lot without. Not having them in a gun doesn't limit me, since I can just grab another gun. But, I can see the utility of screw-ins in some instances.

For that hammer Husky, I'd just have the chokes openned a bit to Mod/IC probably. Mod is plenty of choke from the 16 yrd line and even further while it's open enough to shoot skeet with as well.

On birds vs. clays, all I can say is it does a fair job of tuning up a shooter for wild birds. There are differences, the first is that a broken clay is not a dead wild bird necessarily. The other big difference is that a clay will come out of the trap at it's highest speed and then loose speed continuously. A wild bird is at its slowest speed on its takeoff and accelerates from there. On some upland birds that are larger like pheasant, clay shooters tend to over lead on birds that have just flushed. On quail, they seem to be at max speed by the time a shot is possible and my clay shooting seems to match up well. Some clays are thrown much faster than wild birds, some slower, some the same. Either way, I not serious about clays, but I shoot SC regularly because I enjoy it for what it is, not for what it emulates. Heck, I don't even keep score most of the time.
