Like dr. A said, stay away from the ruger #1 loads, but run a few
different bullets thru it. Mine likes 400 grn speer, and 350 Hornady
the cast bullets I load overall seem to be more accurate. Oh I forgot,
the vaunted 405 Rem shoots really well also. the 300 grn bulltes are
popular, but I prefer the bigger, longer bulllets for stability.
