I'm fairly sure many of them have been altered for scopes but it does make one think about what would happen if one did fail.
G.M.
I think you need to be careful about who you believe. P'14s / M1917s have formed the basis of African Magnum rifles for decades, a budget alternative to proper 'Magnum' Mausers, or heavily reworked military '98s. They've also formed the basis of many custom jobs for very hot factory cartridges and heavily loaded wildcats back in the days when American shooters had military actions gunsmithed.
Both Frank de Haas ('Bolt Action Rifles') and Terry Wieland (Dangerous Game Rifles and Cartridges) speak highly of the strength of remodelled 'Enfields'. So far as drilling and tapping holes for scope mounts, the advice that this is dangerous will come as a great surprise to the owners of thousands of so-modified 'sporterised' Enfields, this usually done following milling the rearsight protecting ears off. Fitting an 'iron' target rearsight also involves drilling and tappoing with some designs.
'Eddystone' manufactured P'14 / M1917 rifles obtained a reputation for having very hard and perhaps brittle steel, so occasional examples were found with hairline receiver cracks. Many gunsmiths say this is also partly or mostly due to the original .303 or .30-06 barrels having been installed using massive (excessive) torque in this factory and the force required for their subsequent removal can over-stress the action. For this reason. most gunsmiths avoid this model for a custom rifle build and use either Remington or Winchester marked examples.
Badger's plan is not original. A considerable number of M1917s were refurbished and rebarreled to 8X57mm during WW2 and supplied to Chiang Kai Shek's Nationalist Chinese forces as part of US support to this group in the war against Japan.
