May very well be due to the volume of gas that stays within the case prior to movement of the bullet. Has the added advantage of a shorter free bore to the leade and no objectionable ring of residue in the chamber with shorter cases. The final trade off is just a different powder to up the power level.

Aliant 2400 I found best for full house .357 with H110 a close second. Worked the other way round in .44.
Good post, this one.

Re: .38-55 - the usual bullet for this calibre is a 200 - 240gr Postell-type, but it is a finicky cartridge to say the least. Much experimentation can be needed to work up to a good load, and bullet moulds are not so easy to find this side of the ocean. It really is a long-range shooter - out to 600 yards, with fancy compressed loads of duplex powder, wads and perfect bullets necessary to get good results.
