Ron does much more work than I do. I have run tac, varget and r-15, all with good results under smk77 and 80. I currently only run varget with 77's because that is what I have. I am to lazy so only run 1 load for all lines and use a powder measure for all. With 24.5 varget I am getting 2775 ft/s which is hot. Some nice pet loads for heavy bullets at the link below.

i have yet to feel my ammo limits me and I post some good scores.
