That would make perfect sense in terms of modern munitions, as to what things will have been developed in the next 200 years or so, we can't say.
Except it's a round that already exists, more or less. To understand the weaponry in Aliens, all you really need to do is look at the weaponry that was considered "future tech" in the 1980's (the film came out in 1986). 10mm Auto was introduced in 1983 and was new enough at the time that it was relatively unknown to all but avid firearm enthusiasts, and since it was something that actually existed they could actually have solid information on what kind of damage it was capable of causing. Caseless ammunition was another technology that was considered 'future tech' - likely because of the 4.7x33mm caseless rounds fired by the H&K G-11 which entered the final stages of development during the 1980's (and went into a limited production run in 1990). Explosive-tipped ammunition wasn't particularly new, though advances were being made in Semi Armor Piercing High Explosive Incendiary (SAPHEI) rounds for infantry weapons at the time. Explosive-tipped ammunition
doesn't function the way people tend to think it does. Each bullet
isn't a grenade. The idea is that you use a small amount of explosive to poke a hole in the armor plating for the round's penetrator to enter through. It works great with incendiary rounds, since you can punch a hole in the armor then ignite whatever is on the other side (these are the rounds typically used against light vehicles, as you mentioned before). But the rounds used in the M-41A
aren't incendiary. The explosive tip is used for no other purpose than to weaken armor enough for the 10x24mm round to pierce through armor that would have otherwise flattened the round on impact.
EDIT:
To the filmmakers' credit, they actually did a pretty good job at mimicking future tech in a believable capacity. Though everything is based on technology that existed in the 1980's, a lot of it is still in a lot of ways considered either 'future tech' or at the very least rather exotic. 10mm Auto, to this day, still isn't a particularly common round. The H&K VP-70's production ended in the 1980's, so it never really got very well-known - making it both obscure
and futuristic-looking. Caseless ammunition still hasn't been perfected, and currently isn't being used by any countries for standard-issue infantry weapons. And Explosive-Tipped ammunition, while used frequently in anti-materiel and ordinance disposal roles, isn't something used yet by any country for standard-issue infantry weapons (since the vast majority of rifle ammunition already fits the same general role as the rounds used in Aliens, which were pistol rounds using an explosive tip to brute-force their AP attributes). So yeah... props to them.

I don't really buy that, there's lots of fancy stuff even today that could be fired from one of those, no reason to assume things would be the same in the future.
...
I'm not saying you are necessarily wrong about anything, it's just that until confirmed by the creators, it's going to take some doing to persuade me you're necessarily right.
I mean, they've got lots of FTL ships flying around, fancy ammunition seems much less unlikely than those.
I'm not assuming anything. I'm going by both in-universe canon
and armorer documentation. You're the one making assumptions. In fact, this whole quote of yours is assumption. Hell, for all we know Shotgun technology gets completely scrapped and there's
no development past current-day technology. See? Assumption can go both ways like that. I'm working with what the creators of the IP have given us, and what they've given us is a real-life shotgun, firing real-life 12-Gauge 00 Buckshot.
