That's basically the load I envisioned Topper. Of course, that was until I started running around town trying to find components.

I wanted Starline brass but Winchester was all I could find. Got my hands on some FF Goex, I didn't see any Swiss powder. I'm gonna try some .30 vegetable fiber wads as you suggested and I think I found a source for some cast bullets.
That leaves me with a couple questions for now:
1. Have you tried Goex and if so how does it compare to the Swill? ...Since that's all I can find I guess I really don't have a choice though.
2. Have you tried .459 bullets in you Buffalo? I read somewhere that .459 might be better but if .458 shoots well then so be it.
Tim, I'd like to load some smokeless as well but as Bikerbeans said "I do miss the big cloud of smoke."
Thanks for the input gentlemen
