100gr. 2F shoots well in Taylor's 1728 10 bore Bess with a .735" ball and .030" patch. In the .75's, a .715" ball and .025 to .030 works fine. Nice crown helps in loading. We've shot 2 1/2" groups at 50 yards with the 10 bore, .735" ball and .030" patch. I gave him a Tanner mould in .740" ball, for use with same patch as before, but haven't shot it for a while. It did about the same. Straight WW alloy for the big smoothie.
