Not being a know it all , you've been here way longer than me .
I have a 429421 and a Lyman and a NOE 454424 . The 454423 has a 20 gr shorter nose than the 424 . The 429421 has a much longer nose and smaller meplat . My 429421 was relieved to .448 bands for a 257 gr bullet ideal for a light press fit in either my 49' Dragoon or papered for Schofield and Colts .
