I just bought two punds of goex cowboy BP and I understand that goex cowboy BP is equivalent to fffg according too what the salesman told me. If the two powders are equivalent than I reckon I'll continue with the same loads. If they are not the same can someone then point me in the right direction for handloads? I have a Ruger Vaquero in .45 LC and I use 200gr and 250gr RNFP. Any help would be appreciated.
