So, I don't challenge field expedients, and experience based knowledge. Forum knowledge represents what has "worked" for individuals in a number of prior situations. That's all well and good.
But what do I know?
I do know that you don't have an intuitive "feel" for the kind of pressures developed by these rifle cartridges. The maximum SAAMI Pressure of a .30-06 cartridge is just over 60,000 PSI.
How do you predict where a brass case is going to split? Along the side? On the shoulder? Just above the web near the base? Primer backing out? A defect in the base or web?
As long as 60,000 PSI vents out the muzzle of the barrel behind the bullet projectile, you're going to be fine. You might have to extract half a case from the chamber, but it won't be a tragedy. When it starts venting out through the action, magazine, or stock, things get "interesting".
So... when it comes to things that I can't intuitively deal with - even after a long stream of "good luck" - I prefer to be conservative. I am at a point where I just don't take this kind of risk. Your results, of course, may vary. When I teach this stuff, I teach the conservative path.
Even Paul Mauser, himself a master gunsmith and designer` lost one of his eyes in an accident while testing a new semi-automatic rifle action.
