If this was a CF rifle you would most likelybe looking for new barrel - but muzzle loaders seem to be pretty forgiving about such things. As long as the ram rod is a softer materialthan the barrel steel, there is generally no damage to the lands and grooves. You might have a gunsmith take a peek inside the bore with a Hawkeye bore scope. As long as it has no cracks or bulges, and it still shoots decent groups. And check the stock screws. I have seen them bend from such a high recoil event.
