Howdy folks the wife and I went wondering a couple days back and we found a CVA 58 cal musket. It looks to be from the sixtys or seventys, it's in very good condition although I have not shot it yet. It is my first 58 cal so I have had to run around and gather all the goodies to load it, I have several other calibers all of them smaller.My biggest concern is the ball diameters vs the bore dia , books show the balls or projectiles to be of .577 dia but lead balls I got with the gun are of .570 dia and with a .015 thick lubed cotton patch , i haven't but will have to use a hammer to seat the ball to the powder. Got any advice ? the rifle is a CVA 58 caliber rifled bore it's called a Souave.The rifle is in near new condition I,ve got to shoot this one tomorrow, I mostly shoot 32s and 36xes goana use FF goex. thanks folks.
