I would suggest the .50 caliber as it is easy to find bullets for it at the gun stores. .50 cal has sort of become the standard caliber for muzzleloaders nowadays. The gun stores that stock muzzleloading stuff invariably have a lot of different kinds of bullets for them, if nothing else.
But there is nothing wrong with a .40 or .45 though. Those plastic sleeved sabot bullets they sell for the .50 cal rifles are actually .45 bullets.
Like some others stated, get all three calibers.
