Might contact RJ Renner http://www.rjrenner.com/ He is something of a Ruger #1 specialist doing both metal and wood. He could even do the light weight treatment on it, install a thinner octagonal barrel and a new trimmer fore end. I would have him do the butt stock too for a complete package.

I have shot the 458 with 45-70 class loads and they are a lot of fun. Jack Rabbits hate it though.
