Great caliber, very flat shooting, lots of speed and energy. For whitetails my favorite load is 52 gr. of H4831, 117 gr. Sierra BTSP, just about tickles 3,000fps..
.25-06 Rem. (120 Sp at 2990) .391 +2.5" +2.0" 3"@145 291
Sight 2.5" high at 100 yds, your still 2" high at 200 yds. Maximum point blank range is 291 yds. So for everything out to 291 yds, just hold dead on and squeeze.
