MR. Dat,
You are correct in what you say. When I started casting I didn't know anyone that did currently cast and only one that in the past cast. I worked at it on my own. Learned to cast good quality bullets that worked and shot plenty of them. Also bought cast too. Still cast bullets occasionally but buy some too. It really isn't hard to cast good bullets. Started reloading in 1970 and had almost no help. Experimented along the way, learned, read, and forged ahead. Learned a lot too.
I guess it made me feel like I accomplished something that I did probably with maybe ten percent help if that much.
