My main concern is not speed. What concerns me with Alliant MZ is ignition in all subpar weather.[/QUOTE]

Well its non-hydroscopic so it won't absorb moisture. And their ad says its suitable for all muzzleloaders. Although that may be so I don't think I would use it in a flinter. I have used it in humid weather in my caplock without issue.
