@Eric Bye, I agree with making the pan deeper to compensate for a too low touch hole. In @woodsnwater's case, his touch hole is too large in diameter (he has measured it at 0.100") so the installation of a touch hole liner and the machine work to raise the touch hole is the optimal approach. His rifle will certainly function, and the large touch hole will allow a lot of heat from the pan to pass through to the powder charge. Accuracy on target will improve with a smaller touch hole and reliability to fire will be good.
