.36 - 100 to the pound, would take 110 (or so) to the pound ball.
Chuck - bit of difference between 18, 147gr. FMJ .356" conicals (or however many Phil had to fire), and a single 65 to 68gr. round ball of pure lead. In the second instance I have observed (post mortum) how 9, .32" round balls of 3% antimony content, fail to make the lungs of a black bear, shot broadside at 15 to 20 foot range - cylinder bore gun, so there was some 8 to 10" or more spread of the "00 Buck Shot. They stopped in the fat, muscle and on the ribs - really made that bear angry - it happened to be a full grown adult, a 6 footer, not a 150pound 3 yr,. old cub. I do not know if a single 15 grain heavier ball would have been any more decisive. It took another load of the same 00 buck shot at a range of 6 feet, delivered to the side of it's head - THAT worked a treat, although that fellow, a member of my riot squad probably needed a change of shorts.
