I'm hoping that means you are going to undertake to test all the ideas, while we sit back and sip a good quality aged whiskey and nod approvingly.
The core stripping I referred to would be the capsule accelerating to spin while inertia kept the shot from following it. At muzzle exit, the greater mass of the shot would slow the lighter capsule much more than the capsule could add spin to the shot. It would be in proportion to their relative moments of inertia around the spin axis.
The term 'core stripping' comes from the phenomenon occurring in some jacketed rifle bullets where the copper jacket is accelerated so rapidly it slips over the lead core, failing to bring it fully to rotational speed. When such a bullet exits the barrel, the core is spinning more slowly than the jacket is, dragging the jacket rotation down while the jacket spins the core up less.
