Doc..With do respect...Tube ignitions in a Marlin Levergun is from pressure/over pressure that takes the bullet and slams it into the primer in the tube full of other cartridges...

Well, with all due respect, I think your understanding of the mechanism of tube ignitions is erroneous. It has nothing to do with pressure and everything to do with momentum.
And momentum is not pressure in a tube magazine?
Why is it only ammo that exceeded the pressures of the 450 Marlin(43,500 PSI) had magazine ignitions?
Why is it the 45-70 has a SAAMI of 28K yet Garret Cartridges ammo was backed up by Marlin Firearms?
None of this has anything to do about revolvers/pistols other than Tom Magnums loads are way over pressure in an 11" barrel.If his velocity is way over the line...Bet me his pressure is also.
