Have just obtained a S/S t/c Patriot in .45 cal,because you use a greased patch which is usually about 10 thousand of an inch the ball size which fits perfectly is .440 cal(any lee mold supplier will have them,I got mine from cabelas)Accurate at 50 metres,I use 12 grains of Swiss 4f,a dream to shoot.If no swiss use 15 grains of any good blackpowder.
