Billy1shot,

I've got a .458 Tropical rifle too and love it. Can you
e-mail me that load info for the 600gr Barnes?

As for the original poster...

Try the 550gr .458 Woodleigh bullets. They come in softnose and solids and both are legendary for their toughness. I've used them in my Ruger #1 and it shoots them very nicely.

Haven't tried the Barnes Original yet, but would like to.
