Use the American Hunter line, with the Interlock bullet. The 155 BTHP (aka OTM) isn't a proper deer hunting bullet. They have the AMP jackets, which are very thin, with no taper, such they're really not a good hunting bullet for midsized game. Wanna blow up colony varmints? Sure, wanna make big splashes on bottles of water, sure. Want to kill deer? No - get the Interlocks loaded in the American Hunter line.
