I started casting with my 357 an 45 colts and all went well with only 2 grns variance in weights and .002 in dia. Dia was attributed to the moulds (LEE) I had 453 s and 455s .and 357-359 . So thinking ... Self you can do this ...... I bought a 324 and a 309 . tried out the 324 out and had a terrible time getting good bullets I had to get the mould HOT like 400 degreesto get good bullets . So is this normal with the "smaller" dia bullets or just a quirk of this 1 mould ? I only got about one in 7-8 in the handle side cavity and about 6 for 10 in the forward cavity . These are Lee 2 cavity moulds "just to get into it" budget . Also how much "harder" are bullets that are water quinched than their air cooled counter parts ?
