I do not shoot a TC, but HAVE had a lot of experience with Investarms Hawkens, 1:48. Hornady Great Plains .50 cal, 385gr. shoot really well over anything up to 100gr 777. 80 - 90gr is probably optimum. Powerbelt 295's also shoot well, but not over 90gr. 777. Never got 348's to shoot well. M/L are kinda individual, so your mileage may vary....A peep works a LOT better than the stock sights, and I have a Lyman 57SML on one of them. You may need a taller front sight tho'.
