Some ballistic info that might make a difference to the OP if he is confronted with a longer shot.All w/100 yd zero.

150gr 2750 200 -4 300 -15
180gr 2400 200 -6 300 -20
200gr 2300 200 -8 300 -29

Expansion @300 may be an issue with 180 & 200 as most are constructed for 30-06 velocity. We have found the 30 150 TSX will
achieve 2 caliber expansion at 1300 fps.
