Ya'll figure these folks just stuffed anything in their rifle and let fly?

They exploited the benefits of cast bullets more than we do cuz that's all they had. WE learned from their thoughts and work. I use 70+ year old molds that are as good or better than made today. Of course they were the custom molds of their time. Most of the so-so stuff didn't survive the trip to today.There were hacks then just like there are now.
