I have bought some parts for old Ideal molds from Lyman and I think Eric the HP man has some of the off size screws that they take . And yes I have a wind problem as well . Fall is my best time for accuray . I have what is called the Delta breeze that has turned into the Delta wind the last few years . And the range I shoot at runs a long a river [ which is our brim ] . It can create its own curents as well . Some times I just have to go out and have fun and not get to serious about it .Marvin
