Lyman 358477: Old? new?

[38-55]

I found an early 358477 SWC mold. It drops at 148 gr. when cast of 50/50 WW/PB. I like that. It is my understanding that later versions drop at 158. Anyone verify that?
I'm just curious. My goto 158 gr. SWC is the old 357443, so the 358447 is a keeper as a lighter bullet.

Mine is about three years old and drops at about 150 grains, which varies some with alloy. I just cast about 500 with it today. Of all my moulds the 4 cavity 358477 is the easiest, fastest, and most forgiving of the all. I almost have to make an intentional error to create a cull bullet with it.
