I got lucky. My Lyman sizing die is marked .379 but every bullet I ever measured that was sized in it is .380 and that .380 size works in my 38-55. There are also folks that will open up a Lyman sizer by a few thousands but offhand I can't remember who they are.
Thanks ... i have heard of opening one up with a drill using emory cloth... sounds like an all nighter thou...
I guess i will go one step at a time and in the end will probably order one special for my Star
