Landandtimber,
I also have used the GS Customs flat nose solids and they are an excellent solid..The GS Customs HVHP is also an outstanding buffalo bullet...
But to answer your question what I like about the cup point is that it expands just a little bit, but that little bit is very effective on all game, and it still penetrates as much as most solids do..I have recovered about 7 of them, and that required a lot of buffalo to get that many as they mostly leave an exit hole..The 40 clibers expand to 50 or 55. the .470 expands to 65 or 70..I can use one bullet for anything I want to shoot..I have shot a lot of plainsgame with them and they work great..I shot two Impala for meat one day and later that same day shot a nice buffalo. I really like them. I have those seven bullets photographed and if you would like to see them send me your email address..I can't post the pictures here, thats beyond my computer ig..
