Jacketed bullets, hmmm, paper patch is a jacketed bullet. If you mean metal jacketed then that would be prior to 1886 when the full metal jacket was invented. Before that wire wrapped we tried I know but can't recall the history with dates.

Smokeless invented 1884.

So the real question deals with the sub-moa accuracy. That would only be a guess for me. Interesting question.
