Just for those who have never treaded into this discussion, there is an article in Handloader this month that re-hashes the reasons why this is not a good idea.
Years ago a scientist of some note spent considerable time on the project. Trying to show exactly why it happens.
About all he proved in that regard from what I can gather it that it's a mystery. It happens every 1000 shots... maybe... or maybe it's the next one...
He went into considerable detail, tested many cartridges, did experiments on different case shapes, lots of stuff, wrote a book on the subject, all in very high tech jargon pretty much indecipherable to most mere humans.
It cannot be duplicated consistently.
BUT, he did succeed in showing that it's possible, and that pressure variations at low powder levels with for example 4831, in large cases occur randomly and at times to high levels possibly related to powder position in the case. Along the way, his extensive experiments, and calculations produced a lot of other very useful information.
Handloader has got together with another scientist, and deciphered the text, and printed a shorter, and more understandable version in this months issue.
It's well worth the read, and if you were a nay sayer to this theory, it may give you pause.
