I want to thank Bill,tinker,and Marrakai for your replies to the post of pics and info concerning the double. My thoughts were to start with a charge in the neighborhood of five drams with the patched round ball and work toward regulation. I would be very happy to achieve groups of four shots(two from each barrel) into four inches @ 100 yds. Anyone care to comment on this? Info regarding the lead sled has been duly noted. Regards.
