There's lots of good information so far and I appreciate the input. Most of it I have already found. I guess I just need to experiment. To answer your question RJM, it is a Ruger Toklat. It's just interesting there is a larger amount of conflicting information than any other round for which I have ever loaded. I like the Lyman 4th edition. Even it is now a decade old. I do like Hodgdon's website. I guess one needs to weed through it and just make determinations of "similar bullets" and then be cautious. Freedom Arms has a great bit of information; but, even then, they are very FA specific, for the most part, for both bullets and revolvers. In addition to hand loading for the 454 being new to me, loading cast bullets is also new to me. It's a good thing I like being educated.
