Talking about a conical, for a TC. My hunting partner, use to rave over the R.E.A.L. bullets. Lee, made the molds, and maybe still does. He was one of the best hunters, that I've ever known. At the time I was shooting, Maxi-balls, and I never got in to casting. Now, I prefer the Patched round ball, however, I am using a round ball barrel. I really don't see that much difference in the 1:48 and the round ball barrel, except I can push it a little faster and maintain accuracy. In the 1:48, I use 60-70 grains, for best accuracy.
