Darryl s, that link was a very interesting read. I don't think I have to worry about effecting external ballistics much as 150 yards will be a long shot. I also believe that there is more more impact sound with the flat nose projectiles. I have notice this when using the 44 mag with flat nosed cast projectiles on pigs.

Rhodes, I have not seen Paco Kelly's article but I will be looking it up. Thanks for that. All I need is a chance to get out and test them, they are loaded and ready to go.
