The relevant scientific literature over the last twenty years from actual experts in the field of terminal ballistics has shown that "energy transfer" is not a wounding mechanism for small arms fire.

You’re confused.

Well, most of what I’ve read about the subject has boiled down to the author’s expectation that someone will simply take his word for it. I am curious, though, about the Dr. Roberts’ quote. I’m sure he knows better than what that out-of-context statement would indicate, so it would be interesting to know where it appeared. If he does believe just what the statement indicates, though, he should try to find a copy of the Wound Ballistics book I referenced above.

Or he might look at the photos in this article. The wound damage depicted there was caused by transference of energy from the bullet to the tissue. Even if we make the narrow exception for the parts that were actually contacted by the bullet, it’s obvious that the rest of the damage was caused by kinetic energy that was transferred to the leg.

To return to my point, however, it’s graphically demonstrated in this video.

Note what happens to the support board under the test medium block about the 4:00 mark: It breaks, and the reason it breaks is because the kinetic energy of the bullet is transmitted (“transferred”) through the medium to the board. The bullet never touches the board.
If that doesn’t make clear how energy transference can damage things like body tissue, then there is no hope.

Swiss P is a brand line of RUAG. If it's anything like their GP90 it's true match grade ammo in terms of QA\QC and accuracy. When GP90 first hit the U.S. market there was a lot of press on how clean and accurate it was. When people started testing the ammo in ballistic jell the downside was the bullet does absolutely nothing in terms of terminal ballistics. The Swiss actually went out of their way to develop a bullet that doesn't fragment.

In terms of choices of ammunition, it occurred to me that employing a pair of linked magazines might be useful for a rifle kept loaded and at the ready. Let's say you keep an AR for home defense, and it might travel a bit, too. In the mag locked into the rifle, you could have your anti-personnel loads; Fusion, Gold Dots, et cetera. In the other magazine, you could have a barrier blind load, for the world at large. Switching between magazines would take three or four seconds. Just a thought.

I ordered the 75 gr. Gold Dots from PSA. What difference exists between the 64 and 75's in terms of performance?

I read a good article written by a fellow who had honestly been there and done that, with the scars to prove it.

having you first load and reload in the rifle makes a hell of a lot of sense.

I did the same but changed it as the weight was a bit much for my lovely better half.

I may be old school but some tape and a small wooden pencil works great.

Also, ensure that you have a barrel twist rate that's sufficiently fast to properly stabilize the longer 75 grain projectiles (1:8 or better). If you have a 1:9 twist rate, you'll want to stick to the 64 or 55 grain Gold Dots. And if you have a 1:12 twist rate you'll want to stick to the 55 grain Gold Dots.

Not quite "anything" in that the thin-skinned varmint bullets may not survive the trip to the target. I have a 1/7 bbl that I cannot shoot Hornady 55 gr SX bullets in for that reason.

True, but AFAIK only the lightest and thinnest jacketed varmint bullets grenade out of a 1\7.
