327 should have the same cartridge virtues as the 357Max, the 32S&W short, Long, and H&R Mag should work too, plus reloadable with carbide dies. Back when Skeeter was still alive and the H&R Mag was introduced he chrono'ed it and the then current 32-20s, the H&R had more beans.
Ive had the 25-20 and 32-20, Id go for the 327, or even the Mag version first, and in a 25 I have the 25-35, which shoots the light 25-20 bullets as well as heavier (faster twist than the old, std. 25-20). If they quickened the twist a bit for a 25-20 I could still see it for heavier than 87gr., but sub, or barely, sonic loads.
The big reason for me in either cal. is that those stubby little light bullets have such a lousy ballistic coefficient, about like a 40-45gr. 22Hornet, and nobody shoots those against longer,heavier bullets at targets or varmints. It would just make the chambering that much more useful and well rounded.
