Does someone have information on the differences between these moulds?
They are all Round Nose 44-caliber moulds of mid-weight (235-255grs).
According to Lyman's Third Edition Cast Bullet Handbook, they list the weights as:
#184 - 235grs
#251 - 255grs
#383 - 245grs
(Cast pics data shows the same weight figures - of course that data is taken from Lyman as well.)
I've found a whopping ONE post here about the 184 boolit that says it was the original Black Powder 44 Russian boolit, and the weight is described as significantly heavier than what Lyman lists. (Presumably Lyman's listed weight is for Lyman #2 alloy, and I don't know what alloy the poster used.)
I'm really interested if anyone can show me the difference in nose profile between them. (I'm sure there are base differences too, but I'm wondering about noses specifically - hopefully with a measurement from the edge of the front band to the tip of the nose, please? )
