I personally would get some .490 roundball and patch material and start shooting roundball just to get used to the rifle. It will give you the oppertunity to see how smooth the trigger is, how fast and sure the lock is, and how you like the sights, as well as the balance and weight of the rifle. After you have shot good groups with the roundball and have not changed the sights to drastically since if your Bobcat is like mine and the sights were not adjustable, then get some of the powerbelts or other conicals and give them a try and see how they shoot. You're going to have to play with powder charges to see what the rifle likes best.
