I had almost thought you might have found some document stating the minimum acceptable dimensions for military spec ball cartridges, silly me.

Having no real information to support your simple statement that Headspace was of little or no importance to case life you just jammer on and attack the messenger instead of the message. That by itself is enough to prove that you are wrong and you know it.
I've noticed a tendency for some to attempt to create their own myths by repetition. Some for instance will claim against all evidence that Cordite doesn't erode bores. Some will claim that bullet to bore fit has no effect on accuracy or that over sized bullets do not raise chamber pressure.
About the most obtuse argument I've seen is the continued claims that the NRA UK withdrew their safety warnings on converted No.4 rifles due to some threat of legal action, which is ridiculous on the face of it. The warning is still in effect and No.4 rifles converted from .303 to .308 must be reproofed to be used in competition or limited to the lower pressure range .308 and 7.62 loadings.
Then there's the claims that warnings on the unsuitability of the SMLE actions for high pressure cartridges originated with some shadowy and unidentified "American gunsmith". That actually originated from the manufacturers long before WW1.
Theres always someone to quote some supposed blow up testing that for some reason left no actual records, and someone claiming that they heard of an SMLE chambered for the .300 short magnum cartridge, no information just unsupported claims. When I've posted documented evidence from the official records of debates in the house of commons the reactions are truly laughable.
The crap from the cheap seats gets so deep sometimes hip boots seem in order.
So why don't you find that document or just stop posting if you have nothing to contribute.
I'll settle for good headspace and a tight chamber while you guys go hunting for rubber bands and tape to make up for lousy headspace and wallowed out chambers or use up the 50-60 year old milsurp while the primers are still likely to work half the time with hangfires you could measure with a grandfather clock. If I had no interest in rifles other than to hear them go bang I'd buy a cap buster.
