I have an old Lyman 358429 that makes absolutely beautiful bullets. I usually load them over 5gr of Unique in 38sp cases, been an accurate load in every revolver I've tried it in. Sometimes I do spool them up a bit with 2400 or Unique to replicate the old 38/44 loads since I have a couple of those revolvers and a 357 Blackhawk that I like to shoot.
My only complaint with the design is that they won't chamber in my Chief Special with the driving band outside the case mouth and I don't want to change the seater setting for one gun. I just feed it 358156s from my HP mold.
I have 358156 and have used it for many years, good mold. I also have a brand new 358429 which I have yet to even heat up...and I've been wondering if I can use the crimping groove for .357 Mag and still chamber ammo in my Black hawk. I am assuming the answer is yes, reading between the lines of your post, but is that correct?
