The pro-argument:
That rifle is over a century old. It has obviously been fired many times, and it's still intact and here.
Decades ago, my father picked up an original unsporterized military form 1903 Springfield. I took it out and plinked with it many times. It was a low number Springfield, but I was not aware of the heat-treating issue at the time. It never blew up.
The anti-argument:
A fellow who posts here paid a lot of money for this Meunier Springfield which blew up on him. I bet you can find the thread.
