I've been followin' this too, and I thought I musta been an aberation too!  ::) ::)   My '73 has been feedin' BP .45s since I got it, with nary a burp!   :D     The cases look just as dirty (or clean ::)) as the ones comin outa my pistols!  Must be sumthin' in the air up here in Nevada Territory! ::) ;D

While I don't shoot 45s I do shoot 38 spl. with the Holy Black in a '94 Marlin.  I have had much trouble over the past with carrier fouling from blow by.  I thought I was getting chamber fouling but determined that was not the case as, when I experienced feed problems, I could easily push the cartridge into the chamber with my finger.  Basically it appeared as though the enrty angle into the chamber was too steep and the cartridge was wedging against the frame. 

I have found the solution to my problem!  I am now using a Redding crimp die (after trying RCBS Cowboy crimp die, Lee taper crimp die and Lee Factory crimp die  - none of which would allow more than 20 rounds to be fired before feed problems occured).  I just finished shooting a 10 stage match and side matches without any intermediate cleaning and the last round feed just as easily as the first.  I am a happy happy man  :) :).

I don't shoot black, so I'm not meaning to present myself as an expert regarding the blow-back issue in .45-Colt.

However, I do know that the .454-Casull is chambered 'very tight' to help deal with the high pressures of that hot-rod round.  If you wanted to test the tight-chamber theory to reduce or eliminate blow-back you could re-size your .45-Colt brass in .454-Casull dies, and shoot the resulting handload in a firearm chambered in .454-Casull.

As for design parameters related to cartridge pressure, I believe the .44-Mag and .357-Mag are close to the same. 

And for what it's worth, you get more blow-back with LOW-pressure SMOKELESS-Powder loads in .44-Mag and .45-Colt than you do in .44-40 and .38-40... this is my experience anyway, as my .45-Colt / .44-Mag cases are much dirtier after a shoot as compared to my .44-40 / 38-40 cases.--CC

I may have missed it in this thread but didn't we used to set the lead melter at an annealing temperature and dip the mouths of the cases in the molten lead until the lead slides off and then drop them into cool water?  Works for me.

Guys, I'd appreciate it you stick to the topic of thread, the .45 in lever guns. I want this thread to helpful to those who are working with that combination. The other caliber discussions are not helpful.

Here's a pic showing just how very well annealing and partial sizing the .45 Colt case works with b.p. ;D
Now that's what I call clean!..........

Happy Trails,
