RE: Doing Semisane's homework
I think all of us have read a few posts about the miracle bullet. I could not agree more. I do find the numbers very interesting. Yet to this date I have never bought a chronograph. I did mention once that I wanted one, but some people do not take hints very well, and I never saw the need to actually buy one myself.
Like you, I am a firm believer in go to the range and see what it will do. Some of the people on this forum must live at the range, with all the information they are able to share. And good information to boot.
To estimate that conical would still have over or around900 fpe at 300 yards, kind of boggles the mind. No wonder the old Whitworth and Gibbs rifles were so deadly.
