On the Internet, it is not easy to get someone to stop typing long enough to read and or listen. Again and again and again evidence has been presented, suggestions have been made etc..
“this is NOT how it is designed or intended to be fired” I do not load to defeat a design, I load with an understanding of the design, again, I do not have a rifle that will allow the case, bullet and powder to out run the firing pin, my firing pins are mechanically operated, by description mechanically operated should suggest to a reloader ‘mechanically operated’ is slow, again, I am the fan of time is a factor. I know the length of the chamber from the bolt face to the chamber shoulder.
That much slop (?) in the chamber is a recipe for destroyed brass or a brass failure'’ Bad habits is a recipe for destroyed brass or a brass failure'’.
On another forum a shooter chamber a round and then pulled the trigger, when he ejected the case it did not have a neck, the ejected case had a case head, case body and a shoulder, no neck, I explained to the confused shooter what happened, immediately I am accused of not understanding case separation due to insipient separation. (stop typing, start listening). No one ask ‘Where did the neck go on the case he fired? No one understood the case shortened .285”, shortened/lengthen, insipient separation is about gad habits and case stretch, again, his case shortened, it did not lengthen, those without a clue do not understand the length of the neck thing.
‘Where did the case neck go? in insipient separation the neck length does not change meaning the case moved forward and locks onto the chamber!!!!THEN!!!!! with the case body locked onto the chamber the head of the case is driven to the rear, the distance the case is allowed to move back when contacting the bolt face determines the amount of case damage and or failure or shortened case life.
I am the fan of cutting down on all that case travel. Most reloaders can not get past the snap back, jump back or case spring back, my cases are lucky they have head stamps, if they want to know what they were before I pulled the trigger all they have to do is check their head stamps, because, after I pull the trigger the case has no memory of what is was before the primer was crushed.
What's that prove?
If the case is not restrained in some way it is totally possible to not ignite a primer.
Wether or not your extractor holds the cartridge case against the breechface tight enough to fire, this is NOT how it is designed or intended to be fired. That much slop in the chamber is a recipe for destroyed
A boring story, good for listeners, not ‘typers’ , I have fired 8mm57 ammo in an 8mm06 chamber, for those that are listening that is the equivalent of .174” difference in length from the head of the case to the shoulder/datum and chamber length, the shoulder of the case being fired was not driven to the front of the chamber (as the story goes, the firing pin drove/launched the case forward and the case stopped when the shoulder of the case came in contact with the shoulder of the chamber, then! the primer went off etc., my opinion, that story should start with ‘Once upon a time’)
The ejected 8mm57 case did not have a neck, the shoulder of the fired case did not move forward, it was erased and became part of the case body, the new shoulder was formed when the case filled the chamber from the neck meaning the neck became the shoulder, so it goes with forming, again, no one scribes the case body shoulder juncture, no one scribes the shoulder/neck juncture.
