In a so-called "controlled feed" action, extractor engagement depends in part on support of the round from the chamber. In other words, unless the round enters the chamber part way and fits reasonably tight, it can be loose enough to drop out of the extractor. IF the extractor is tight and the case head is the right size, that shouldn't happen, but things are not always perfect.

I think the problem you are seeing is due to the .22-250 being both shorter and smaller at the front than the .270 case and things would be OK in a .22-250 barrel.

But if you are serious about wanting to keep or go back to a .270, then buy a .22-250 rifle and keep the one in .270 that shoots so well. There have been rifles made with interchangeable barrels but they cost as much as two ordinary rifles.
