So I am relatively new to casting. I have done some tumble lubing for my 357 mag with the Alex, Johnson's paste wax, and mineral spirits. I just purchased a lyman 4500 and wanted your opinions on what lube to make/buy for it. I am looking to push a 44 mag 250ish keith bullet, plain base to 1200-1300 fps. Also a 170 keith style plain base bullet in my 357 to 1100-1200 fps.
Should I just buy a certain commercial stick lube and slap it in there or make my own?
Thanks in advance!!!
