Friend, really not trying to be nit picky here but let's be serious. I really don't care if a premium bullets has a bent nose and I am not going to call said bent nose expansion. I would encourage you to read the many threads lately about premium hunting bullets penciling through animals and causing all kinds of recovery grief and in some cases lost animals. Most all of them were due to lack of sufficient impact velocity. A softer bullet like the A-max would have eliminated many of those issues IME because they open up wonderfully at the lower velocity levels that LR hunters find themselves at.
Proper placement with the right bullet and adequate energy would have made the difference.
Can I ask if you have ever hunted with the A-max?
Already answered. Long ago. After watching several hogs and deer run off after being hit right in the bread basket leaving us with long and difficult tracks because there was so little bleeding due to the fact the bullet never exited I learned my lesson.
Also, the difference between the 6.5 140 gr A-max and Interlock is .12 in BC, not .065.
Pardon me I was looking at the SST. There is no 140gr interbond in 6.5.
At 750 yards that is 15 less inches of drop, 11.5 less wind drift, 211 more fps, and 225 more ftlbs. I will take that any day, twice on the weekends and never look back.
You know I don't even carry a ballistics calculator or weather meter and I manage to kill much smaller targets than deer at that range and beyond with the .260 shooting 130gr interbonds and sciroccos so I don't see where such a crutch is necessary. If you are however using field calculations then having the proper variables entered eliminates the guess work.
Even if the A-max and SST are compared the differences are still 7 inches of drop, 6 inches of wind drift, 105 fps, and 115 ftlbs. Same bullet weight, same velocity out of a 260 Rem.
So? That's why you have a ballistics program.
At 1000 yards and beyond the differences blow up. When you are talking vital zones of 8-18 inches and are dealing with cross current winds, updrafts, etc. I will take everything I can get.
I can only think of one word that is really fitting for the use of a 6.5 at over 1,00yds on anything bigger than coyotes with any bullet, and that is "irresponsible".
The key is knowing what your bullet is capable of and being ready to make a change if needed. Again this is why having a close range bullet that impacts very similar to your LR bullet is such a good way to go IMO. You get the best of all worlds!

No the key is using a bullet that is going to perform consistently and reliably at any range you pick within the practical limitatios of the caliber.
Before I'd use the Amax in the scenarios you describe I'd either go to the Scirocco or Berger Hunting VLD's. Much better choices of bullets.
I've got a very large 3x4 freak of a buck I've been watching for the last few weeks. If The shot presents itself my ambush set up will have me shooting him at between 800-1080yds. If he's under 900 I will use the .260, and if beyond I will use the 300 Rum. Both will be loaded with the Sciroccos and I have 100% confidence that the bullets will do the job even if I get a direct strike on the point of the shoulder.
At the same ranges I'm getting nice 1.5-2" exit holes on coyotes consistently and the doe I shot at 600 two weeks ago with the .260 gave similar results.
Shoot what you want. I don't care, but I will continue to recommend that quality hunting bullets be used in hunting situations to anyone who asks because that is what they are designed for.
