My goal is to anchor the animal DRT with a full on shoulder shot to prevent leaping off a cliff,
my question is what would you use ... the 178 gr or 208 gr AMax ?
specifically for shooting those two animals dead square on the shoulder at ranges from 100 yards out to 600 yards
also what are your thoughts on the use of the Hornady 208 gr and 225 gr BTHP Match bullets for this application ?
I think the 208 AMAX is the best bet, but I've never shot a Dall sheep or a Mt Goat.
My reasoning is this:
1. You really want to keep the impact velocity under 2900 ft/s. In the thin mountain air, the 178 AMAX may retain higher velocity for a long distance.
2. Hitting shoulders at 600 yards can be iffy. The 208 AMAX has the best chance to both expand and hit either the near or the far shoulder if you can't line up both shoulders.
3. The Hornady 208 and 225 gr BTHP bullets have unknown performance in game. Many open tipped match bullets are iffy on game, and I'd presume these may be also unless there are definite reports over a wide range of impact velocities.
Nothing is definite with shooting at 300-600 yards. Wind, angles, and elevation can play havoc with shot placement. I think the 208 gr AMAX minimizes the probability of another bad experience, but there are no guarantees.
We've shot a lot of deer (hundreds) with ballistic tips and the 110 VMAX at 30-06 and 308 velocities. Rapidly expanding bullets can drop a good percentage of animals immediately without hitting the shoulder, but the best chance of an immediate drop is always to hit a shoulder. In addition to great terminal performance, the 208 AMAX also gives you a great chance to hit a shoulder at long range with its high BC and accuracy.
Another thing we like about the 208 gr AMAX is that if you take a longer than expected shot at long range and impact below the expansion threshold of the bullet, the bullet tumbles and still has very good wounding effect due to such a long bullet moving sideways.
