My 32's like 160-180gr everything. Although I home cast 2-bullet weights for most of my shooting use. Both are g/c accepting. Otherwise I wouldn't bother to cast em.
321497 & 321427. 427s purpose? Little 134 gr'er primarily used for night time vermin seen moping around in the grass under the yard light or diddling with the lock on my Gasoline storage tank. (the latter be-gets a warning shot so to suggest: "Best get to quick step'in out of the yard"
As far as powder measure?
Accurate powder brochure or

Powder? whole different ballgame from what other 32 special shooters prefer. My preference>AA-2223 being a ball like powder has proven to be a tad more stable (shot to shot) & accurate propellant I think better than 30-31. Since I don't have scopes mounted on my 32's I require the tightest {eye sight} groupings from a powder I can get. 2223 works for me.
Alliant is also a pretty good powder to load. Only problem with its use is its sharp muzzle report.> (loud)
