Big flat on the front is better than a jacketed bullet too. I have some experience with Nosler Partitions and they are really good but they are REALLY expensive too. The old Keith boolit and Veral Smith's long and wide flat nose boolits are about as good as it gets IMHO. I have a friend who is a feral hog killing machine and he shoots my cast boolits. He tells me that he has not lost one since he started using them and they were running off and dying somewhere he could not find when using jacketed stuff.
