I have been doing some research for loading 45-70, and I came across this picture:
It was posted in a thread, and it happened to have data for the Lyman 457124 bullet that I'm researching. I'd appreciate it if someone who recognizes the source (I believe its Lyman, but no idea which book) would chime in.
I wish I could find samples of the 457124 bullet to measure, but I found some measurements on buffalo arms site that will suffice for my load development for now.
Does anyone know the history of the 457124? It must have been discontinued and or not very popular because I can't find much about it.
Thanks for looking all,
Bazoo
