You must be resizing them the entire length of the case wall - including the web - all the way down to the extractor groove - to form a kind of semi-rim. Do they extract OK?
Otherwise I'd think that they'd just drop too far into the cylinders since they are too short to headspace on the mouth. I'd like to see a picture of some of those modified cases.

Yes, they have to be full length resized and the web has to be swaged down in the sizing die.
You start with a sized 45 acp brass, then size it in a 44 sizing die in increments, and you keep the brass wet with lube, otherwise you are courting disaster.
A sized 45 acp case at the base in front of the extractor groove is .471.....resized in the 44 die it becomes .465 and the rim of the cartridge is .476.
So the extractor will index and pull the case out, as you can see in the photo with my wife holding the Bulldog.
You can see the swaged web on the case on the left in the photo of the before and after photo.
While this can be done, I would never bother doing it while I can obtain 44 spl brass.
But this process is one those options a reloader has if he or she cannot find 44 spl brass.
