Sir Woods,
Good to see you here, and Sir Mike too, we can only hope.
The .458 WinMag does it all.
Even if they don't let Brandon go free (Let's go Brandon)
we know how to make paper-patched and BP work in the .458 WinMag, if it ever becomes a necessity.
While we can still get smokeless powder, and needing to conserve on premium bullets as inflation turns them into worth their weight in gold,
it would be good to imitate the ballistics with hardcast.
I have never gotten the 400-ish-grainer hardcasts up to 2500 fps,
to see if it is practical regarding accuracy and whatnot for practice and plinking.
I plan to do it from 72.0 to 80.0 grains or more of AA-2230, AA-2460, or H4895 up to 110% compression, whatever it takes ...

Previous experiments around 2000 to 2200 fps MV with these were excellent, using AA-2495 benchrest powder.
