Lee,

I've always found the XPB bullets interesting. I've even wondered whether I could dip the .500 275 grain in lead and resize in orderto use full bore (unsaboted)as a legal conical in Colorado. I haven't tried to, though, because I suspect it would fail for accuracy due to the lack of sufficient obturation of the all copper XPB.

The bulk XPB's would certainly save money. Also, the new TMZs offer ballistics on par or superior to the XPBs so you might alsowant to look into them.
