The hardcast are painted blue.
The 20:1 are painted red.

One possibility is to size the 20:1 "Red Death" Bagwell Bullet down to .453" from .456" as cast.
Then ram it down the .452" bore of the CVA Paramount, atop a charge of Blackhorn 209.
Scope sighted muzzleloader might allow even a caveman to mimic Saint Sir Bill Bagwell's BPCR with barrel sights,
in ballistics at least, even if not in superhuman accuracy.
The caveman is still doing the aiming and trigger pulling.

The same bullet might also be paper-patched up to .459" and loaded with duplexed BP in the Norma .458 WinMag brass.
That would be "special" in a .458 WinMag (1:14" twist)
or the surrogate .45-100-2.6" Sharps Winchester Throated (1:18" and 1:20" twist).
I am thinking grease cookie, paper patch, PC paint, and smokeless starter under BP to match the compressed BP ballistics of .45-70 Govt.
Could shoot all week and never have to blow or wipe.

Like Sir Jerry said, the possibilities are endless,
with a SAAMI-chambered .458 WinMag.
I only have about a million unfinished projects lined up for it.
