Wub welcome to the forum. Good to have you here. As for what yours will shoot... I can tell you what mine likes..
80 grains of Triple Seven 2f and a patched .530 (mine is a .54 caliber) roundball. Deadly accurate and all the gun a deer would need.
You might want to go to CVA and download a manual for the rifle. Get the manual for a Bobcat. Same rifle, different name.
