If there were truly burnt receivers it's hard to understand how they got out of Springfield Armory and Rock Island Arsenal.

I have never read a report of any failures on the battlefield WWI or WWII. The Ross had problems in WWI and it was wildly reported.

Ordnance Went Up Front by Roy F. Dunlap Samworth 1948 (speaking of low-number rifles) I saw hundreds of these in the war, used with all types of issue ammunition including armor piercers with a rather high chamber pressures. These low number actions are safe with practically all government and commercial ammunition in .30-06 caliber, with the possible exception of very high-pressured target loads or heavy-bullet hunting cartridges.
