Chap,
That is an interesting article- I've been trying to find again it since the first time you posted it! It got me started looking into articles on hardcast handgun bullets and hunting with them. When it comes to muzzleloading projectiles, I think there is more similarity to large caliber handgun hunting than there is to centerfire rifles. Look at both muzzle and impact velocities, there is a lot of similarity with common ML loads. Granted, when you start bumping up charges you're in the realm of 30-30 centerfire performance so there is some hybridization that must be taken into consideration.
That being said, the most effective handgun hunting loads feature a large meplat (frontal diameter) flat nose and steep shoulders, they also happen to be hardcast lead. You are correct that they do not expand much, but the wide flat nose causes a "splash" which translates to shock and a ragged temporary wound channel. Lots of very in depth writing out there on that subject- the guys that hunt with the .454, .460, and .500 are pretty serious about their game.
Reading up on the subject is one of the reasons why I want to get a good load worked up with that .44/270gr. Gold Dot flat nose soft point. It may be the best of both worlds...

Exactly right, velocities around 1200 to 1600 fps are hand gun speed and once you get to about 1800 or 2000 that is 30-30 speed, and in fact I tell people that the modern ML is basically a single shot 30-30 from a ballistics POV. I believe the ML bullets are better than the old round nose 30-30, because they make some pretty effective ML bullets now--Barnes TMZ, MZ, Nosler Partiton, etc.
From a COST, performance, penetration POV I agree 100% with you on the large frontal area cast bullets. Ignoring >>cost<<, I believe the Barnes does it all at all distances, with good expansion, excellent penetrationand pass thru. If your gonna go non-cast and you want the cheapest best commercial bullet available, then in my mind that is the Gold Dot, no doubt because of it's cost ($16 for 50), bonded, so it stays together, shoots thru becusse the weight and large frontal area gives they big splash. I am still learning a lot about these things also...my journey has been.......
Knight 240g all lead in Knight Sabot in knight Disc for 1st year I hunted--didn't know squat about ML bullets
Then PowerBelt 295 for 3 years in Knight Disc and TC Omega, didn't know squat about ML bullets, my brother got me into PB because they load easy.
Then Nosler Partition for 3 years in Omega---got educated on bullets...
Then Parker Ballistic Extreme in Savage 10ML shooting smokeless, this year. Got more education on bullets......
I love the Parker's accuracy, don't like the fragmentation on bone and it is great on "bow shots" into the vitals....jello... Excellent expansion because of bullet design (some liquid in the center to cause expansion).
Best Wishes on your Bullet Education Journey,
Chap
