If it is really a hundred years old I probably will not be shooting it anyways.
As long as it's not damaged, it can take it. I have an M96 with a 1901 receiver and a CG63 with a 1903 receiver and shoot them at least once a month.
Swedish steel is tough, it'll stand up to regular use. Not to say you should get stupid with it and handload beyond normal 6.5x55 pressures, but good handloads or factory loads are good to go.
If you've never shot the 6.5x55...you're in for a real treat!
