I have a CVA hawkins and a two Traditions Woodsman Hawkins. Two of them have a 1-48 twist and one has a 1-66 twist. I also have a Traditions Pioneer with a 1-48 twist. Oh ya.. and there is a CVA Stalker Carbine, and a CVA Tracker Carbine. All of the 50 caliber. All of them shoot roundball excellent.
To tell you that a CVA Hawkins 50 caliber will kill deer is easy.. yes it will. It depends on shot placement, range and your own skills. As for telling you the load the rifle will like is a little harder. All rifles are different. BUT ON AVERAGE I find that 70-85 grains of 2f powder, a pillow tick patch, your favorite lube, and a roundball will give more then satisfactory results in the accuracy department.
I cut my muzzleloading teeth on a CVA Mountain rifle. Not a better shooting rifle, was there. It was a .58 caliber mind you, but it was a CVA. Normally they make a good rifle.
