Going by the .458/600 gr Ranger FMJ bullets I've seen, I would not choose the Game Ranger Bullets Marstar is selling. I just checked Rhino's sight and they have a very good soft point, but no solid. Then I thought for sure Woodleigh would have what you are looking for, but no luck there either.
Are you planning an exotic adventure that you want solids, or do you just want to try them?
