Here is a tipped MZ (250gr.) I pulled from just under the skin on the opposite side on which I had shot her (quartering away shot) dropped in her tracks (100yd shot). As I began field dressing her my buddy had noticed the ballistic tip in the pool of blood where she had lied...... 100% weight retention again.... The bullet weighed in @ 251 gr. because of the meat still stuck to it. All I can say is Barnes keeps impressing me each time I use them.
