ORIGINAL: .308hunter

For the past couple of years I have been using Core-Lokt 150 PSP's out of my .308 for hunting deer. I haven't had any problems with them on deer, but whenever I recover them form newspaper or sand they have always framented apart. I am concerned that they may do it in a deer and I was looking at other bullet options. This summer I was working with the 180 Partitions to use for black bears this fall and I like they way they shoot. I know that they are made for deeper penetration, so I wasn't sure if they would be acceptable for deer hunting. I wonder if they will expand fast enough to take a deer.
Has anybody used these bullets to take deer? Will they expand enough? Any insight you guys can provide will be greatly appreciated.
