I am going to get a bit more into shooting cast and making my own bullets. I have a chance to pick up an old Lyman 45 Sizer and Luber at a reasonable price and was wondering how good they are as there are two newer Lyman models available out there. In the research I have done, one source said that they will not seat and crimp gas checks. Is this true? If so, it may not be the machine for me. Any info and opinions are appreciated. Thanks.
