I just acquired a Kimber Caprivi in 458 Lott and I am looking to load for it. I am strongly considering 500 Grain Barnes Triple Shocks for my softs but I am unsure which solids to load. I have read that flat nose solids perform better than round nose solids so I am looking at Woodleighs or Noslers solids. Is there an merit to this? Do any of you load any of these in your Lott's? What are good powders to start with?
