Note that an MSM launcher can fire a smaller missile, although the smaller launchers cannot fire MSMs.So you won't need either a sabat or a sleeve for a SD to fire a BC missile out of it's capital missile tube. Another example would be the ability to fire a Mk-23 missile out of a tube built for an Apollo control missile.
There's not enough information in the note from that infodump to know whether or not a sabot (or other supplementary mechanism) was needed to let an MSM launcher fire a smaller missile. That was an aside to the post, not the main point so it would be entirely normal for RFC not to have elaborated on exactly what was require to take advantage of the capability. But lack of mention does not mean no special device or mechanism (like a canister or sabot) might be required; absence of evidence is not evidence of absence.
After all it's a basically true statement that any artillery piece can fire sub-caliber shells. But it's incomplete because the first part is only true when you use a sabot to adjust the sub-caliber shell to the larger caliber barrel.

You're accelerating at 500 gravities, and if you release one missile per tube every 12 seconds, how far are your missiles strung along? I don't have a handy spreadsheet for this, so if my math is wrong please forgive, but it looks to be around every 416m you'd be leaving a missile? Can someone confirm that number?
And that's still assuming that floating your missiles out doesn't get them vaporized by your own wedge as you keep accelerating. Unless you're accelerating 180 degrees AWAY from your intended target, and you're only dropping missiles for a short time, you can no longer guarantee getting 100% of your SDMs to even reach attack range with time left for terminal maneuvers or deceptive attack runs.
Well you're accelerating so the intervals aren't even; but fortunately I do have a spreadsheet of missile performance I can easily reporpose to this. Lets assume you are accelerating at 500g, that the salvo interval is the 12 seconds you mentioned, and you have the fire control to handle a crazy 10 salvo delayed launch.
Note 1: For simplicity I'm going to track the missiles from a single tube because the interval between each missile in a given salvo do not change
Note 2: I believe RFC said at least once he uses 1g-Honorverse = 10m/s^2 but my spreadsheet is still using 9.8)t=0s; d=0km
t=12s; d=353 km; interval=353 km
t=24s; d=1,411 km; interval=1,058 km
t=36s; d=3,175 km; interval=3,175 km
t=48s; d=5,645 km; interval=2,470 km
t=60s; d=8,820 km; interval=3,175 km
t=72s; d=12,701 km; interval=3,881 km
t=84s; d=17,287 km; interval=4,586 km
t=96s; d=22,579 km; interval=5,292 km
t=108s; d=28,577 km; interval=5,998 km
The missiles are strung out, at increasing intervals, over about 30,000 km. On the one hand that sounds like a long way. On the other that's less than one half of one percent (0.41%) of an SDM's max powered range of over seven million km!
Also assuming the target is accelerating just as hard on a parallel course the aftmost missile will also need to make up an additional 529km/s of velocity due to the target building up that vector perpendicular to the missiles normal flight path over the last 108 seconds. Which
also sounds like a lot, yet it's the equivalent of ~1.2 seconds of the missile's drive (at it's normal 50% power setting).
If you had the fire control links to talk to all those missiles the distance and velocity they'd have to make up seem easily surmountable issues...
