Use published data with blue dot and do not worry. Remember everything on the internet is true. Refer to handloader magazine propellant profiles for an explanation of the warning about blue dot in 41 and light 357 bullets. They changed it a little when they cleaned it up and alliant did not reshoot data with those cartridges so they cautioned against using it with their old data. The 50 th Lyman book and I think Speer has current data in those calibers. Use modern data. I do. Shot some 44 mag blue dot loads this evening. Good stress relief
