inherited a 1917 with a pitted barrel from my dad

That old Enfield rifling definitely can still do the job even when it looks pretty sad. Get some M2 ball or equivalent (150gr bullet at an advertised 2700 fps) and see how it does for starters. I've been shooting an M1917 with a rough bore since the 1970's and it still shoots 2-3 MOA if the nut behind the trigger does his job.
