Spitpatch- Sorry I wasn't more specific on military actions. The "gas guns" are definitely less capable of handling pressures we would consider normal in a Bolt Action. Loading .223 to bolt action specs can be a disaster in an AR. Likewise for M-1's, M-14/M-1A's. Have you noticed how some manufacturers are now marking the headstamps of their .308 ammo "M1-A" when sold for use in a 7.62x51 "gas gun"?
As for the 1903, it's one of my favorite rifles and I shoot one regularly. It appears to be the basis of the Remington 700 design minus the extractor claw and third bolt lug.
I also agree that proof pressures are not to be used as targets but merely mentioned them for the purpose of pointing out that modern rifles are tested way beyond the published "Max".
Almost all of the catastrophic failures I have either witnessed or observed the results of have been the result of other than high pressure loads. Obstructed barrels from squibs and wrong powder/double charges are the other most common.
What's really interesting is that almost all of my "difficult bolt lift" incidents have involved Factory Ammo.
Here you are on another forum spitting your bogus information as usual. Gas guns, military or civilian are designed to run at lower pressures than bolt guns. In my experience, which is obviously a good bit more than yours, is that M110s, Larue OBRs, GAP10, ARMALITE SASS models, all run at a substantially lower pressure than say the M24. Theres this thing called carrier bounce that happens with AR-10 pattern rifles, if the load is too hot the gun feed reliably. And M1As dont explode when you run them hot, the piston just cracks and the oprod batters, you can make a simple adjustment to the gas system to take care of that.
