Some of you may remember my recent post about my 338, which I bought for an upcoming "hunt of a lifetime" with my dad next fall. I was perfectly content with my 30-06 until I was convinced by a few that I should get a magnum for that possibility of needing extra oomph for a long range or quartering-to shoulder shot. I bought the Tikka and love the feel and fit of the gun, but still doubt if I really need this uber-thumper. I got to punching in some of my loads into the Hornady ballistics calculator the other evening and this is what I found:
30-06 180 NAB 2750 fps mv, superb accuracy, 100yd energy 2644, 400yd energy 1727, 3" high at 100yd, 18" low at 400yd
30-06 165 NAB 2950 fps mv, superb accuracy, 100yd energy 2776, 400yd energy 1787, 3" high at 100yd, 15.5" low at 400yd
338WM 180 NAB 3000 fps mv, acceptable accuracy, 100yd energy 3119, 400yd energy 1771, 3" high at 100yd, 16" low at 400yd
338WM 200NAB/210TSX 2900 fps mv, acceptable accuracy, 100yd energy 3568, 400yd energy 2000, 3" high at 100yd, 17" low at 400yd
As you can see, the 165 actually outperforms the 180 in 30-06 due to the extra 200fps mv, and by the numbers it really doesn't lag too far behind the 338 200/210gr loads at 400yd, with slightly flatter trajectory. I'm not a believer in energy from a bullet killing an animal, but I do believe that it can represent the ability to drive said bullet into and through the vitals for effective tissue disruption and bleeding. The energy numbers are all more than sufficient for elk within this self-imposed 400yd range. My only real concern with the 165NAB is that quartering-to shoulder shot and if the bullet will retain enough mass to carry it through, so I'm going to try to get similar velocities and accuracy with a 168TTSX, which carries a very similar BC.
This 30-06 is silly accurate and I have a great deal of confidence in it, and don't really want to get beat up by the light 338 if it doesn't offer a truly sizable advantage. Have any of you had any luck breaking 2900fps with the 168TTSX in 30-06 with I4350 or RL17, or would you just stick with the 165NABs?
Thoughts? Would this be better suited for the hunting section?
